Question ideal fuel pressure???

need to no ideal fuel pressure on an idi. truck is a 1991 7.3 auto with dual ram air hood scoops straight pipe and water meth injection. when the pump was set a little hotter than stock it held 4-5 psi. the other day he turned it up ~3 turns and it would never get above 3psi so tonight we put a holley blue(110gph) electriclift pump on and regulated it to ~5psi at idle. keeps constant fuel pressure at this setting just curious as to what kind of pressure these trucks like?

4-5 sounds right I think I remember no more that 7?

Remember, we aren't eating this stuff, we're turning it into diesel fuel. Your truck only cares about viscosity, acidity, and BTUs. Nothing else. -unknown?
NC State law defines biodiesel as ''any fuel or mixture of fuels derived in whole or in part from agricultural products or animal fats or wastes from these products or fats.''
