Message	is to pinch off the return line to the tank and see if the fuel pressure rises. The FPR should go on the return line back to the tank from the rail. Pinching the return line will cause the fuel pressure to rise.If it rises than more than likely the fuel pump is good...if it stays low..check the pump..pump voltage or pump controller... So I'm having this dream! I'm in my Z and these guys are after me, but they can't catch me...So they get a car, but they still can't catch me. So they get a plane, and just as their about to catch me....the TWIN TURBOS KICK IN!

(n/m) - ZLover4Life 14:00:12 07/28/08 That's what I was thinking, but he's tapped in before it (n/m) - Pushin'twins 14:02:26 07/28/08 Yep, it is directly after the fuel filter - Drk93TT 14:03:26 07/28/08 lol that doesn't exclude it from being the FPR. (n/m) - ZLover4Life 14:04:15 07/28/08 My Dampner and FPR I beleive are OEM - Drk93TT 14:07:40 07/28/08 The best way to determine if the FPR is bad ..... - twinturbineZ 14:17:47 07/28/08 or you could have an obstruction in the fuel line (n/m) - twinturbineZ 14:19:14 07/28/08 thats how the FPR works - AntiHero 14:12:50 07/28/08 that what you're supposed to do.... (n/m) - twinturbineZ 14:22:06 07/28/08 I had an issue with fuel pressure last year after my swap. - kkrofft (OH) 14:11:59 07/28/08 should I replace with OEM FPR? - Drk93TT 14:15:36 07/28/08 Im reading posts that OEM works fine - Drk93TT 14:28:51 07/28/08 yes, it does (n/m) - BigTDogg (MA) 14:39:25 07/28/08 thx tdogg (n/m) - Drk93TT 15:14:26 07/28/08 Works fine doesn't mean it is correct.
