Re: Fuel Pressure

Stock fuel pressure can be between 41-47 psi. For instance mine was 42 psi. The injectors are rated at 43.5. The PCM compensates for the differances, detected by the 02 sensors, by narrowing or widening the pulse widths of the injectors.

Re: Fuel Pressure

The stock pressure of 41 - 47 psi is with the vacuum line remove from the fuel pressure regulator.

If never going past boltons then a stocker will suffice, if looking to really mod the car then a Walbro is a good idea even if you haven't quite gotten to the mods yet.
