p7100 fuel pressure
My girl friend has a 95 12V, (see my signature for mods), we are running her fuel pressure guage off of the top of the stock fuel filter. She has a raptor 150 lift pump. Once we installed the guages the fuel pressure is only reading 12psi at idle, and when you stand on the throttle it reads almost "0". My questions are 1) What is the correct Idle, and WOT fuel pressure she should be showing. 2) Can I achieve the correct pressure with turning up the fuel regulator on the raptor lift pump?
Im not to savvy with the 12 valve engines, but the motor is pretty decently built and I would think it needs a lot more pressure than that.
thanks for the help.
