Fuel lines for FPR install

[stevo86]

Hey fellas, new to supramania, i just started usin in cause the forums are down. Im in need of some help. Im lookin to install my areomotive fpr. I know i need a 12mm to -6 an adapter for the fuel rail, a -6 an male to male hose, then another hose with a -6 an on one side, and a fitting to connect to the fuel line comming from the fuel pump. My question is, what fitting do i need to connect that -6 an braided line to the stock fuel lines? Thanks for your help.

---- bump

for the return i would just get a a -6 to a 3/4 (or whatever the size is...) nipple to use the stock return line. its just easier that way.

You could probably use flare fittings, and flare out the factory hard line. I went through the same thing two weeks ago, it turned out to be way too much hassle to find all the right fittings and lines. I just ordered a premade kit with all the right fittings (and also bypasses the J-tube) from Suprasport.com

theres only one SS line that needs to be assembled if you use just a hose barb for the return. really no hassle at all. save some $$ and still have something that looks and works great.

I have the flares and fittings you need. I have regular non braided lines on
my car now, (have the aeromotive RRPFR), and I have since bought all the
stuff to make the shiny braided lines, etc. You interested in my old setup?

It would be the line from the fuel rail (including the fitting for the fuel rail)
a rubber EFI line, line to the the RRFPR, the end for the FPR, and the return
line back to the car. Its all rubber stuff, not shiny stainless, but it has
worked great for me. The only parts you wouldn't get are the fittings that
attach to the aeromotive FPR itself. (I need to re-use those)

I used to have a write up that showed all the fittings, lengths needed, and how to assemble the entire fuel system. Lots of nice pics, part numbers, and everything.

lol, so helpful but yet it isnt. :slap: lol. is it completely lost? ill need this soon as well.

I'll look for it see if I cant find it. It was posted here before the crash.

sweet that'd be cool if you had a write up, its nice to learn from others mistakes than your own! thanks for the offer on your old setup jtamulis but im lookin for braided lines.. im plannin on runnin some higher fuel pressures to make up for the smaller injectors. Im goin 1/2 NA-T. The only other thing i'd like to know is what size the hose is that connects to the back side of the J-Tube. I wanna run a line stright from there to the FPR to bypass the J-tube and its restrictions. But i need to know the hose size to get the proper size -6 AN to hose barb fitting.

higher pressure like what 300 psi?

SS braided lines are more for looks and perhaps abrasion resistance BUT they are wear items just like normal hoses.

haha no, like 70 or 80 PSI at full boost, i have a RRFPR too. The hose i was lookin at gettin is 250 psi max, i was just gunna get about 6 or 8 feet of it cuase i need to make some turbo oil lines too and figured i'd might do it all from the same hose to make it easy. Then all i have to get is fittings.

70 to 80 psi??

wtf??

dude that is nearly 30 psi - 40 psi of boost? Be hard pressed to get that much boost out of stock or even an upgraded turbo. Need a BIG turbo along the lines of a gt42r and up.

It's not that hard and you don't need a big turbo to do it. A big turbo has nothing to do with it anyways. Raise the rail to a higher base and you're there. Base 45-50 and only 20-25psi on the turbo to hit 70psi rail pressure. Much like you could go the other way if need be, drop the rail to 30psi if you've got larger injectors.

It's how you work smaller injectors for more hp. As long as you aren't going over about 85% capacity, it's perfectly fine to do that.

This is tuning basics...
