Max pressure for Fuel PSI?

[Dalpilot]

What should be the bottom end? I know the low side is 45.

 

[nghtrgr]

IIRC the high side is 75

You haven't removed the duct tape yet. LOL







I think the high side was 60 to 65 psi and you did not want to go over 75 psi.

I was thinking 70-75 was MAX.

Probably getting paid at work to post this from my D1

With my 225's anything over 65psi would cause a rough idle. I can only guess that the fuel was being pushed past the seat in the injector. But I ran pressures as high as 100psi. with the pressure boost referenced with no issues I could pick up on.
