Pinto Efi Fuel Pressure

[Guest Dan_Beeston]

Does anyone know what pressure the standard Pinto EFi fuel pressure regulator runs at (with no inlet vacuum)???????

 

Cheers,

Should be 2.5 bar with throttle wide open and drops down as vacuum increases. The pump supplies around 70 psi whatever that is in bar so there is always fuel returning to the tank. It is not easy to check as there isn’t a tap off on the rail unlike most, so you need to put a gauge in line with the input to it then power the pump to run with engine off.

1 bar = 14.5 psi near enough
