I wasn't sure if this belonged here or in conversions, so i picked here.
I have a 99 Firebird that i'm trying to finish up swapping a 98 LS1 into.
When i prime the fuel system, I'm reading 70psi on my fuel pressure gauge. At idle i'm seeing 90 psi...:eek:
I'm at my wit's end and am convinced it's something stupid and easy that i'm just overlooking. The engine is completely stock minus a set of TSP Longtubes and an LS6 PCV conversion. The in-tank fuel pickup was replaced with one off of an 00 SS so that i'd have the fuel pressure regulator. I'm still using the 99 v6 fuel lines, but i believe lines should be the same size.
I've considered swapping to a vette LS1 fuel rail to utilize my return line again and get the FPR up on the fuel rail again. I still have my v6 pump assembly with a racetronix pump that i can swap back in.
Any ideas at all? I'm stumped and really want to drive my car again. It's been two years since the last time. :(
