Mr-C Posted October 29, 2018 Share Posted October 29, 2018 Hey gang, I've been chasing a Lean condition and thinking now its related to my FPR. I just installed a Glow Shift in-line fuel pressure gauge (on the feed line) and PSI is stuck at around 30psi at idle with and without the FPR vaccuum line removed, which in both cases is under spec per the FSM. Revving the engine to 2000 rpm doesn't change anything either. Any further test I should do.....such as pinching the return line to see is psi increase? If its a faulty FPR should I replace with the original or go with the 07' older STI "mod" i've been reading here? *Note: I have stock injectors which passed flow bench testing and a new DW65 fuel pump and gas filter which has all been installed 5 months ago.
