Default RS-T : SVX FPR swap... fixed the idle pressure problems

After installing the fuel pump (Walbro) in my turbo kit, my fuel pressure raised from 33psi at idle to 44psi at idle, causing the ECU to have to lean it out at all times 10%+. The WOT non-boost pressure used to be 44psi, and then became 58psi. This brought it back down to stock perfectly.

I got the FPR by calling junkyards on www.copartfinder.com and finally found one in Nebraska. Shipped for $35 - much better then the new price of $250.

I did have to run a new vacuum line to it, though, because the stock one was 1.5" too short and it kinked when I tried it. Also it was loose on the fitting on the FPR, so the new, smaller hose worked great.

Thanks to ARG for the inspiration and the <a href="http://www.i-club.com/forums/showthread.php?s=&threadid=54567">great big pointer</a> you posted so long ago.
