But I don't trust the guage as it also can read 6 at times, Guess I ought to replace it sometime.
the pressure starts out at 6.5 lbs and goes up from there depending on how much boost is being produced. but the fuel pressure is never more than 5 or 6 lbs. more than the boosted atmosphere pressure. So the fuel isn't, or shouldn't be, blowing the float needle open.
