The pic in post 371 looks like a truck fuel rail, hence why the connections are at the back driver's side...

The pic in 372 will work assuming you have stock fuel line location in the car...

The one in 373 looks as if it would work with a little tweaking of the angles of the fuel lines, as well, though I've never seen one exactly like that.

I've heard of folks using the truck 5.0 rail in a TC, as the 2.3 cars have their fuel lines running up on the firewall, nearest the driver's side, IIRC..

I like the idea of an adjustable fuel pressure regulator, but I probably wouldnt use one.

The vacuum is essentially an built in adjustable regulator. When you are on the gas, you lose vacuum, it automatically adjust fuel pressure to suit. The computer knows what it needs. You start messing with the fuel pressure,bit no longer does.

The computer can only compensate for about 10% difference from the oem tune. That's part of the reason I hate the 10% ethonal garbage we have here. It makes up a whole 7% leaving you for just 3% or so.

A lot of the adjustable regulator's need would determine what pump you have, look at Vinnie's setup....if uses that big FP he's talking about, he's going to need an adjustable if he doesn't have one on already...

I don't think a SD EEC compensates for a whole low in regards to fuel pressure. It merely can be tricked into cycling the injectors for a certain duration. Would require flashing the chip though.

Mass air EEC though is a different ballgame, and Scott had ought to be on that path, with a stroked engine...

Basically, I had a SD HO in my 'Sport with a 255 Walbro pump, ran like a scalded cat and didn't need a afpr. Never tuned on it, so I'm not going to say it would've ran better with a little less or more...who can say.

I decided to go with this fuel rail.

and,, did you all know............................................
**inside the vac acuated fuel presure regulator there is a screen on the large opening? A filter so to speak,,

swapping over the blue top injectors now.

hope i dont screw myself by going with a two bolt FPR, this one will require vacuum like normal but i really wanted to be able to recycle the CFI FPR's if you all thought it would be useful. these FPR's for early CFI applications are pertty cheap to buy at the box stores.
I took one a part one day for the heck of it, to see how it worked and if i could recycle one into a hydraulic ram valve we have down in the creek,, i noticed it also has a filter.
thats when i was telling people to just shiznit can thier injector screens, the fuel is getting filtered three times,, once at the tank sock, once at the fuel filter then once again a the FPR.

the fuel pump i have is walboro,, i need to look it up but 175lph sounds about right,, maybe 200, not that this car needs that.

apparently cfi V6fuel lines are much much longer than 5.0's. I am trying to follow the same fuel line path as the 5.0, 3.8L came in behind the pass strut tower.
i tried to keep that and it simply looked like .

i have plenty of hose to reach the fuel rail extentions by following the 5.0 path., but not without some customiztion.

What injector are you going to run on the 331?

there is absolutly no way i will use this fuel rail. fit testing and it all sucks.
i wish it were not true but it is, its honestly a very good looking fuel rail.

the return line fitting is in conflict with the coolant rail temp sensor.
the supply line is pointing "into the upper intake.
these two things above i would be able to work around if i was desparate but, when i felt back at the FPR, i said hell no. the one allen bolt would be impossible to remove , the angle of the FPR and one bolt would not be accessable for my son in the future.,, SCREW IT ALL.

I will go with another fuel rail with the help of my pal Rocky!

here are the problems with this fuel rail mentioned earlier

so off comes the purdy "different" fuel rail from some stock ford 4 wheeler we cant identify yet to another fuel rail.

this one is purdy clean but i really want to have a shrader valve test port on the rail. neither of my fuel tank metal lines have a test port so i need to work on this.

here is the one i will use, bonus is it will accept the CFI 3.8L FPR thats adjustable. We will install a vac operated one in the meantime and if chance wants an adjustable one, the solution will never be expensive. after all , there's always "dads garage" to supply parts.

so to drill out a spot for a fuel presure test port....... i saw this done on another fuel rail i have so i get to it.
i discovered that the metal block i am working on must be made of a material that is not on the periodic table.. yes i have good quality bits.

i put a magnet near the drill area to catch all the stuff flying around.

i tap the threads and in she goes.

this is a very nice looking fuel rail , no blemishes at all, nice and prudy.

humm,,
it just clicked ,,,,,,,,,,,,,,, wonder if any of you gents ever thought of this....

add a fuel presure test port to both the supply and return lines. this way you can troubleshoot fuel delivery problems and it would either point to the regulator or the fuel pump back in the tank!!

im gonna have to stare at this for a minute and see if i can actually do that.

A stock Fox 5.0 fuel rail has a Schrader valve....

my 20th test port is on the fuel rail adaptor line, not actually on the fuel rail
