Fuel Pressure Regulator. Says 46 PSI to 52PSI with vacuum disconnected.
I know it should be around 39PSI.
I got the new BBK Fuel pressure regulator
that claims 35psi to 70psi
i also installed the BBK Liquid-Filled Fuel Pressure Gauge
AFTER I installed the new Fuel pressure regulator..... SO I DON'T know what it was before I did this
If i loosen the regulator till the top is off the lowest it will say on the gauge is 46psi.
What could be wrong?
