Title: Fuel Pumps-Anyone who has bought a new one?
Post by: jpc647 on January 11, 2011, 04:06:05 PM
Anyone replace a fuel pump in an 86-88 Thunderbird/Cougar with a Stock 5.0? What about in an 88 thunderbird/cougar with a 3.8? They the pumps should be the same.
What pump, brand, model/part number did you use. It shouldn't matter what cluster you have, I don't think. There are pumps available which look like long skinny soda cans which supposedly work and are generally under $100, and there are factory looking replacements from Bosch for example which run upwards of $250. What can I use? What is the most economical way to do this, should I have to?
For Example, from Rock Auto. Notice the difference between the Bosch looking pumps and the delphi one.

I used a Mustang GT pump on my stock hangar assembly ,,it looked like the fed154 or ep356 in the above chart

hmmm... interesting. But you have an HO. I wonder if there is a difference, they do use different injectors and so forth.

I swapped my pump WAY before I did the HO conversion ,,,no problems at all

Interesting. I'm going to do a little research now. Look up mustang ones and see if they are the same part numbers, etc. The one that came out of your car, it looked like one of the bottom ones from the picture, right? The small tube shaped one fit right in the original hanger and plugged right in? It was a stock 88 thunderbird with a SO 5.0 at this point? Do you happen to have the receipt or the part number?

It mounted right in place of the stock pump on the stock hanger ...it was an Airtex pump #E2061

Post by: jpc647 on January 11, 2011, 11:24:48 PM
And you had this on a stock 5.0 in the beginning, with stock computer and injectors? I looked at one of them for a mustang in a parts store, and I couldn't figure out how it would connect to the stock hanger. I should have brought my old leaking pump with me, to actually have both of them there and compare, but stupid me didn't. Maybe I'm just over complicating things. How can an airtex pump be so cheap and work, and the BOSCH one look identical to the factory one and be so expensive, lol.
How long has it been in the car? Is airtex good quality? It came with a strainer and such?

My particular pump was never in a Mustang , I bought some stuff from a guy on craigslist. an H-pipe, an HO upper intake ,the fuel pump and a few other items ,,,the pump was brand new in the box with the receipt , I did have to buy a Bird specific strainer, I dropped the tank pulled the pump/hanger assembly and swapped the pump . I sold Airtex pumps for yaers when I was in the Parts business and they had comparable quality to any other brand pump in my experience . As far as how long its been in my car I want to say I put it in in April , but my car has only gone about 400 miles since then .

Now we're getting somewhere. Now the ebay auctions lists the "right vehicle", but a different pump.
http://cgi.ebay.com/ebaymotors/EP361-FUEL-PUMP-FORD-MUSTANG-85-95-V8-5-0-85-97-V6-3-8-/120662688797?pt=Motors_Car_Truck_Parts_Accessories&hash=item1c180e841d then there is http://cgi.ebay.com/ebaymotors/Airtex-E2061-Electric-Fuel-Pump-FORD-MUSTANG-97-85-/200517777308?pt=Motors_Car_Truck_Parts_Accessories&hash=item2eafca779c which is the right part number, not a lifetime warranty:(.
Which one? I'll buy stuff on ebay from powersellers and stuff if there is a lifetime warranty, other than that, it scares me a little. If the $28 works, i'll gladly go that route, if not, it'd probably get it from a parts store, for the same price, roughly.
Airtech directly list the Thunderbird and Mustangs Differently. Tbird is E2024 mustang E2061... what could the difference be?

I replaced my stock fuel pump with a BBK 155lph fuel pump about 6 months prior to doing HO conversion. It ran fine with my SO engine. It was a lot smaller than the original pump but it still sat down fine in the original hanger and has worked just fine. http://www.summitracing.com/parts/BBK-1527/

i use the super charge 3.8L pump offered by adance , its 90L/hr vs the 60L/hr stock bosch.
the one i can get is "just the pump", no hanger, no shock absorber bushing, just the pump and a couple clips and a new little hose and anew oring for the top.
The last one i bought was 40 some odd dollars at adance.
oh yeah, it does not include the sock either, i had to rig up my sock to fit the sc pump.
either way it fit in my hanger assembly and i had enough parts to get the car working correctly again.

I used the one for 85-88 thunderbird, the 190 LPH. Walbro are very, very good pumps. Its all I use on my Fords.
Title: Fuel Pumps-Anyone who has bought a new one?
Post by: jpc647 on January 12, 2011, 08:47:35 AM
cassity, is it a 90lhp or a 190lph? Can a v8 possibly use that much more fuel?
I feel like I might be beating a dead horse here, but if I can spend 30-40 instead of 85+, or even a 200-300, it'd like to.

Its a return style system, what isnt used by the engine is sent back to the tank. I dont want to run short on fuel when I do my modded 5.0 HO.

Which one? I'm confused. You mean what isn't used when you shut the car off? If it's the Walboro one, what does "with kit" mean. Does it come with the strainer/filter, etc.?
Title: Fuel Pumps-Anyone who has bought a new one?
Post by: mcb82gt on January 12, 2011, 05:43:18 PM
The kit came with the filter sock that goes on the end of the pump intake, clips, I think the rubber insulator? The fuel is always circulating, from the pump to the fuel regulator in the engine bay. The engine only uses what is needed and the extra fuel is returned back to the tank. Its is a constant continuous process.

Post by: jcassity on January 12, 2011, 10:24:08 PM
no typo,, stock came with a 60L/hr pump the 3.8SC had a 90L/hr pump.
what is the advantage,,, its the amount of time you loose stepping on the pedal to feel the quickest most instantanious engine response. We are talking about 1/4-1/2 sec waiting. One other advantage to the higher vol pumps are that when they do start to internally wear, they may put out the required pres even when they are fairly defective where as a 90L/hr pump at lets say running at 50% its best due to wear / age could start to offer poor engine response and such.
Another benefit is the pumps ability to supply fuel pres at a higher psi when the engine needs it the most as during or in between shifts at high rpm's. Idealy you want to have your fuel rail saturated with fuel 100% of the time with max manfactures specification fuel pres appearing on your injectors, however this is not possible with the stock pump. Any pump with more L/hr than stock is better., otherwise the higher end fuel pumps offer no other scientific advantage. I am not speaking to quality or anything else.
the trade off is the same ole story, you get what you pay for.
I am pretty sure that I can buy the 90L/hr pump for my simple street style driving and pay my phone bill with the money i saved.
its your call, either way if your shopping, id honestly look for a USA made pump for the sake of economic condtions if your in a situation where you have to buy one.
Have you put a fuel pres regulator on your windshield and drove the car and watched the guage ? and if so, what was the lowest level it reached. It should drop in presure in between shifts even on an aod.
The higher the revs, the lower the fuel pump pres. The cheaper the pump (lower L/hr) the lower the pres will be at high rpm points.). Acceptable PSI at 3500rpm+ is in my opinion only about 25psi. If at any point you come close or near 20psi, your pump is not meeting the demand game anymore and needs replaced. IT was nice to redo my test and seeing 31psi in between shifts on my aod which represented max rpm of the previous gear.

Post by: jpc647 on January 13, 2011, 12:48:31 PM
I'm not sure what you mean about the pumps cassity. You said you could buy a 90l/hr pump and save money, but that's what you bought. So you bought the cheapo one, but are not recommending others to do that. I just don't understand what you were explaining, I'm sorry.
I am having my father look for a gauge with a long enough hose. I don't have one.

I'm going to Ebay and getting one of the 255lph pumps for $45-$50.00 and give it a shot (yes,it's made in China). Will it out on me? Maybe....maybe not. It has a one year warranty, and with the fuel pump access panel in the trunk now, it's a 5 minute job, so, why not?

I bought mine from APE and it came with the correct sock too which is a plus. If you never used the wrong sock for your FP than you never experienced the false empty tank at 2-3 gallons.

The 190 is cheaper at JD's, only$85, that is about as cheap as you are going to find for a quality pump. Just get it and be done with it. Do you really want to keep dropping your tank when the cheap ass China knockoff keeps going out.......I dont.

I'm going to find out how the cheap a$$ Chinese knockoff pump works out and I'll report the findings. As I stated,with the panel in the trunk,it's a 5 minute job. I'll just carry the one I have now in the spare tire well as a "just in case".

A stock style (Flow, psi, & volume) H.O. pump is more than adequate for most street driven combinations. However, there is nothing wrong with fuel pump overkill, think 255lph. The setup in my stang is running a 255lph Walbro pump and i have all the fuel I need for the nitrous im going to spray. Just do yourself a favor and buy the best pump you can afford. Unless you put an access hole in the trunk like Vinnie did you're pump will out when you have a full tank of gas. Ask me how I know...

Do you have a template? I would gladly cut a whole in my trunk to do this. Hell, part of it is rusted anyway. Can I have dimensions to the hole from the side of the trunk, etc? Please, please please? lol Give me details on how to do this, haha.

you explained that i controdicted myself and told others what to / not to buy which is unexplainable.
im just the dood over here trying to help and ending up looking like an ahole when im not.,,just simply stating the facts and pointing out the possible options you have and to include reasons why one option may not be what you want while the others are better.

I was not trying to make you look like an ahole. If that is how I came off, I a sorry. I think I understand. a 90l/hr pump is what you have and if when it starts to fail. it's still usable because it'll supply enough fuel where a 60 wouldn't. I was thinking in my head, a brand name 60l/hr pump might offer a longer life than a cheapo 90l/h pump. I do appreciate your help cassity.

honestly, i had to make mine because i didnt think i would need to do this test again.
i bought a water guage that went to 100psi , some hose and clamps and a fitting that i modified to attach at the test point on the rail. I have a fuel pres tester but its hose is too short, shouldve bought the extention hose.

Alright, I tested the fuel pressure. Duct taped it to the windshield, and my father watched up. It never went below 29/30 psi. It went up towards 40 when accelerating or with a load on the engine, ran the car around for quite a while, didn't get low.
I drove to boston today on the mass pike and the car did it. It is right around when the car shifts into overdrive, I almost hear a momentary ping, and the car seems almost "confused" as to whether or not it wants to shift into overdrive. If I get into the car a little, stepping on the car, the car seems to straighten out. Keep in mind the check engine light comes on. Could there be a tranny problem? Does OBDI even High Tech enough to know if there is a tranny problem? It doesn't store a code for the issue. I ran codes when I got home tonight, got the same ones as always, 67, then a 1, then 63 and 33. Whatever the light is, I doesn't store a code.
So now we know it's not ignition, its not fuel related... What could it be!?

Doesn't look like the right filter (sock) to me plus the output hole is smaller than the walbro unit I put in a couple of years back. With that filter the car would be out of gas at 2 gallons when I used one like that.. Plus on hard turns it would run dry with under 3-4 gallons of gas

good show,, obviously your fuel pres is good. I am surprised at your findings,, your presure should have dropped as your RPM's increased in each gear.
Ok,, not fuel pump related.
No your AOD will not store codes., so I suggest you get your tail under the car and look at the moving parts from the fire wall down to the transmission with respect to your shifter linkages. Not to say EECiV is not able to as it was also used during the E4OD transmissions, I dont know. Never had one show up on my Bronco, never will since i swapped in a 5speed to the 351 EFI.
You may find that there is a broken plastic bushing on the parts that rotate agains each other. This will add unwanted slop in the transmission. Also, you should adjust your TV cable up at the throttle body to eliminiate irreguar shifts. check my diy link, instructions in there courtesy of V8Demon who figured it all out.

No, its not a joke,, its in the shop manual to tape a fuel pres guage to the windshield and drive it. I thought it was my own idea ,, then i found it as a test step one day a couple years ago in the manual.
As you can see, it was a perfect real load test to truely see the fuel pump performance. Nothing like this can be simulated in the garage with the car in park. At best you get static pressures under not so noiminal conditions,,imho only, im no expert.

Ill shoot in the dark,, get yourself a cheap buttstuffog meter and measure the TPS Im betting you will see a momentary open in the TPS.
Most of the time a tps will work a worn out spot inside it. What i mean is that at the same position (as with relation to the position of the gas pedal) the problem should occure. If you happen to notice the problem is pretty much in the same gas pedal location then your on to something. when your ready to read the tps and need help, let us know,,easy to do.,,in the diy link as well.
What car did the eec come from? seems odd the trans code however, the transmission range selector switch may be mis aligned just do to the very reasons i pointed out earlier having to do with the plastic bushings being broken or missing.
code 1 is nothing more than a separator pulse,, ignor it but go to the diy link to understand what its doing.

Well the fuel pressure did drop between gear shifts, it wen’t from about 40 or 39 psi down to about 35/36 psi, then back up if under load. At no point did it drop below 29/30 psi though.

I don’t know if it is a transmission code, but the check engine light stays solid, for the occurrence of the event. I was mistaken originally. I will look underneath the car, I know the bushing seemed fine a month ago when I was underneath it fixing the floor pan. I will look in the DIY link for the adjustment up on the engine side. I know Ford makes a replacement set thing for a couple of dollars, I might order one up just for some assurance, if it isn’t an arm and a leg.

Ill shoot in the dark,, get yourself a cheap buttstuffog meter and measure the TPS Im betting you will see a momentary open in the TPS. Most of the time a tps will work a worn out spot inside it. What i mean is that at the same position (as with relation to the position of the gas pedal) the problem should occure. If you happen to notice the problem is pretty much in the same gas pedal location then your on to something. when your ready to read the tps and need help, let us know,,easy to do.,,in the diy link as well.
What car did the eec come from? seems odd the trans code however, the transmission range selector switch may be mis aligned just do to the very reasons i pointed out earlier having to do with the plastic bushings being broken or missing.
code 1 is nothing more than a separator pulse,, ignor it but go to the diy link to understand what its doing.
I have a meter, I’ll check the TPS again. I’ll try and try it, again the problem only happens sometimes, usually when going up a hill, but the TPS doesn’t know whether or not the car is moving up a hill, right? I know 1 is the separator code between the “active” problems and the ones the computer has stored in the past 30 warm up cycles or something. The engine was originally a 3.8, and yes, the 5.0 engine harness complete from computer in passenger side kick panel to engine/fuel injection, through to the connectors on the driver’s side next to the fender/firewall. Both the computer and the harness are out of a 1988 Mercury Cougar. I don’t think it’s a gremlin, only because the car has been in its current configuration for like 2 years, and it only started to happen recently.

I still think your dist is in wrong, or your timing chain slipped a tooth. If your still getting a TPS code, your TPS is bad.

I don't understand how the dist. could be in wrong. I don't really understand how the distributor and timing work, I know it's set for about 12 deg. The TPS was from vinnie, so it's a good part. I guess I can check it again, and try another one, if I have one.
The only way to check timing tooth by tearing the car apart?

Now when checking stuff, can you point me to the link in your DIY that shows a person how to properly adjust the TV cable. I see a couple different threads and it seems to be a case by case scenario. Is there a general procedure? Not out of the manual? The one in the manual was done on my car.
Maybe I'll have to take it to a tranny shop? I know there is a ford replacement for the grommet, I have to find that too. Would an out of adjustment(slightly) TV cable cause a check engine light of any kind?

Nope. The EEC has no idea what the AOD is doing.

Interesting. So under no cirspoogestances could the check engine light be related to a transmission? Because it almost feels like a tranny slip, like the car doesn't know if it wants to shift or not. I know the TV cable can be adjusted to allow for a firm shift, or a "soft one". I think mine is in the firm area, sometimes the car jerks a little bit when shifting, but it's always done that, even with the v6. So it's not out of the ordinary, but I would like to try to adjust it, but I'm a little scared. The shop manual description is confusing, and when I followed it the first time, it wouldn't shift out of 1st. But eventually I got it.

The right way to check it would be to tear it all apart. When I did my timing chain, I had it ripped apart and back together in about 3 hours. Not fun though.
I would mock up a piston stop and see where your top dead center is compared to your dist. and timing pointer. would tell you all you needed to know. If your getting a tps, it means it is bad. Good used parts go bad sometimes. Every thread you have is completely different from the next. You need to make ONE thread, and actually put in it what you have done.
If you don't belive that the computer has nothing to do with the tranny, coast in your OD, shut off the key (careful not to lock the steering wheel) and floor it. The engine is off, but still being spun by the transmission. It will down shift and slow you down with the engine off.

I figured. There is no way I’m tearing the car apart in 20 deg weather. Can’t do it.

We did this like a week after the intake gasket swap. We brought the number one piston up to tdc. And set the dist. My dad helped me with this.

I agree. My threads tend to start as one problem, turn into something else. I lose track myself sometimes. I thought I had a fuel problem and was looking for a correct fuel pump, but it seems I don’t have a fuel problem in this case. ,

This is what I was looking for. I just wanted some confirmation from someone who knew, that it wasn’t connected in any way. Knowing the transmission can’t cause a check engine light, is a relief. I’m still going to try and adjust the TV cable though, see if it changed anything.

its V8Demon's thread, it was not really all that hard, just pry the lock tap, grab the cable and pull slack out, then relock. 2 minutes tops to adjust.
your tps may have come from vinnie or god but if you dont measure it using an buttstuffog meter and slowwwwwly rotate the inside while watching the meter for a needle deflection, then you dont really know if its good or not. set meter to R x 1 touch red and black lead together zero out your needle to zero ohms. unplug tps harness hook your meter up to the black and green wire of the TPS and set your meter to R x 10 or the next lower scale. rotate the tps slowly and watch the resistance change(ie- open slowly your throttle body) do the rotation slowly,,,very slowly any deflection means you do not have good contact.
do the same test with your meter on the green to org wire.
all this can be done on the car with the tps still mounted.
next time you get a chance, bust open a tps,, the variable resistance part is just a piece of plastic with a carbon layer in the middle. the wiper arm (green wire) is just that , a tiny arm with a brush that rubs the plastic carbon film.
