Fuel Pumps-Anyone who has bought a new one?

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.

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.

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...

I've had three fuel pumps go out on me since 1987. Every time was with a full tank of gas. Last summer was the final straw. Hole in the trunk...new replacement panel...goodbye headaches.

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.

Stay patient. I'll pull the carpet and snap a pic next week (it'll be warmer) for you with some measurements.

I explained why i did not buy an expensive pump.
I explained why I upgraded to a pump with a better L/hr divery
I explained its your call
I explained the best way to actually troubleshoot the pumps performance


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.

honestly, i think you may just speed read posts,,no biggie.
