Just installed the HPX and FPR on my truck. I seem to have just a slight more vibration at idle now. No difference at all with throttle.

Having some difficulty at the moment, in sourceing items for a fuel pressure
guage. Will able to put one together in a few days.

If I do have excessive fuel pressure will it do any damage to the engine?
Thanks guys.

The only thing you would really put at risk at all would be possibly your fuel pump, but they will usually just blow the gasket on the fuel bowl at really excessive pressures.

 

when i had 100psi fuel i had lower mpg and a load fuel pump.
i think the lower mpg was the leak that came about from the high psi.

 

Thanks for reply, guys. I am slowly acquiring all parts to assemble the guage. Can't seem to find a shrader valve. Any suggestions?

Thanks, Matt. Haven't had much luck locally.
