Here are my terms

1) intank fuel pump

2) all black everything

2) keep the metal fuel lines from the tank



I'm only going to run between 300-350rwhp and this will be total overkill, but as long as it isnt detrimental then i figure why not. I don't mind spending the scrilla



Going for all new injectors, 720/1680cc



As for the pump I'm looking at the walbro 255, or the Bosch 044 which is total overkill but I'm strangely attracted to it.



I was thinking of sticking w/ rubber hose, but had a brainfart and thought to use SS line but w/ some self fusing silicone tape (banzaiwrap). The tapes supposed to be good for 500 degrees.



Then I even found some black nylon fuel hose

It's supposed to be quite lighter though, but only would be like 5lbs. I'm only beeing super **** about weight w/ my brakes and wheels. But I'll take weightloss even if it is by not gaining weight.



I found a couple black RRFPR's, but they seem to be single inlet only.



I was planning on running the rails in parrallel, and seemed like most people ran dual inlet pressure regulators for this configuration. I'm Y'ing a single line from the tank to both rails.

Ted uses -6 line and fittings for the single feed, then splits to -6, and combines back to a single -6. so no bigger or smaller lines.



Holley -8 single inlet and -8 single outlet 15-65psi

Trick flow -6 single inlet and -6 single outlet 30-70psi

As for fittings, earls and jegs make black hard anodized fittings. aeromotive makes a couple but not as many.

Hose clamps

So hmmm, what do I want from you guys.....



What max psi should I look for? Are FC base pressure 35 and FD 45? It's a high comp turbo motor, but I'm running water injection too, so maybe a max of 15psi if the waterinjection and HKS stock mount play nicely.

And is this pressure range on the rrfpr's the total, or does the boost increase this on top of that rating? Thats how it reads for the holley. If so then either is plenty



uhm, i lost interest in my thread cause it took so long to type up, it looks pretty copmlete to me





oh yeah, what about pulsation dampeners?





any input/suggestions are appreciated

Why 720cc primaries? I'm using stock 550 primaries with 1300 secondaries with everything else stock (except replacement in tank pump). Put down 350RWHP with this setup with good duty cycles.
