Fuel pressure

Hey all,

I was after fuel pressure at idle and WOT for '92 5L.

Fuel pressure should stay somewhere around 38-40psi, throughout the rev range. The fuel pressure regulator keeps it at that pressure all the time. If it drops below that, it means your pump isn't keeping up.

30-45 psi is the acceptable "Engine Running" fuel pressure for the 302 and 351.
