I'm having a fuel pressure problem, and hopefully resolve it without having to tear the whole fuel system apart. Here's what I have. 2003 Mach 1 with a Procharger H.O. kit. Fuel pump is a new Focus SVT pump, a new FPDM, Kenny Bell Boost-A-Pump, set at 10%, 42# injectors, and a Pro-M maf matched to the injectors. I only have 15-18 lbs of fuel pressure, and I'm pulling 20 inches of vacuum at idle, 800-850 rpm. Air/fuel is full rich, and plugs are black and sooty.
