HP500EFI fuel reg questions
I have a Hp500 EFI that had a detonation problem last year and I never figured out the cause before we tore it down. Its back together and I want to take some steps to make sure I don't have a fuel side problem this year. The motor is all back to stock specs except .030 over. What are the steps I should take?? I was thinking Fuel press gauge in dash/ new fuel pump/ flow inj/ and was wondering do I need a press reg on the rail and what one do I need?? Thanks

There is a regulator down on the fuel pump assy already...ASM makes an adjustable
regulator that fits in the same location.
