Has anyone else bought the Hescoe adjustable fuel pressure regulator for the
Moport MPFI kit? The 4WD catalog is claiming 44 PSI, but I'm only get 33
PSI. Anyone else out there with a similar experience?

Thanks.

Hesco's adjustable regulator was made by Edelbrock. But the one they show
now is different from mine.

Full pressure (70psi) on mine is only reached at low vac (wide open throttle).

I do see Bernie got the new heads made and the dual TB setup for strokers.
I still think it's way too much air for even a 4.7. Not that I wouldn't
say no to being a test vehicle that is. :)

Bill,

Thanks. Tried that, and it put me on a path. The pressure will go up to 50
PSI if I pinch the line, and that's when I realized that I still had the
vacuum line attached to the regulator. If I pull off the vacuum line, the
pressure immediately jumps to 44 PSI (as advertised).

I assume, then, that this is correct (and -please- correct me if I'm wrong).
As engine load (and fuel consumption) increase, the vacuum on the fuel
pressure regulator decreases, causing more fuel (at the same PSI) to be
delivered to the fuel injectors.

Thanks.
