I'm about to buy a fuel pressure gauge to go on my fuel pressure regulator does anyone know what psi it should go up to? They have like 0-60 and 0-100. Autometer good enough?

I'd go witht the 100 max. Even though the normal would be half that amout, any testing could be done with that meter.eg fuel pump straight pressure to 90/95.

FSM test procedure for max pump output indicates approx 92 psi.

Regulated fuel pressure is 37 psi + boost pressure. Example, 20 psi boost will result in 57 psi fuel pressure. For better measurement accuracy, pick the narrowest range possible, ie 0-60 psi if your boost level is below 20 psi.

If you want to check maximum pump pressure (as opposed to regulated fuel pressure), then as Rob500 mentioned, a higher pressure range will be needed.

well i just need something to tune it somewhat. so i guess i'll go with the 60psi one
