Fuel Pressure
I have installed an isspro fuel pressure gage and need to know what should the pressure be at idle and at highway speeds 60 mph. The engine is stock.
1999-- 3500 dually
Thanks in advance

Make sure it's never less than 5psi no matter what. 10-20 psi is best. The factory LPs are know to have issues. Find an aftermarket one that best meets your needs/price and install it. Upgrading this should really be mandatory.

What pressures are your seen off your gage right now? I think I would like to see 10 or above to get the warm fuzzy the pump is getting the fuel with some consistency.
