Another One of Those Single Turbo Conversions

I still need to figure out the final fueling setup. Clearance is definitely tight in the back, especially after I had to drop the fuel rail to get my injectors to seat properly (didn't want to buy injector hats).

Are you referring to running a y connection to the front? I suppose if I do it that way, I could block the end of one side, and run my FPR on the other. Hmmm.

You Should use for booth " front and rear " Fuel feed -8 AN and split to Y connection with two -6 AN in to the front rail and same way back to FPR. On my S4,A4 fuel line from the thank " feed " was connected to the front rails and back of the fuel rail to FPR, that way your pressure should be equal up to FPR. If you cap rear fuel rail or loop them together then your fuel rail pressure will be different specially between 1st and 3rd cyl. My fuel setup was fine for 700WHP and I used Fuelab FPR for my last build. Also you can loop back of the fuel rails together and use any side of the fuel rail on front to feed fuel and another side back to fpr should work too. Good luck with the build.
