15 volts at the gauge

The old pump was in there for a year or so with the light on. I don’t see a sticker on the fuel line also I lifted the bed off

I’m getting gas Thru the return its throwing a check engine light p0172 p0175

Was thinking maybe bad grounds or something is wrong with the fuel line

Nope I’m getting fuel back to the tank

Also replaced the pump under warranty still same issue

I double checked my gauge with my other Silverado it read correctly

Hello, I have a 2002 Silverado 2500hd 6.0 im currently having a issue with fuel pressure. It’s just way to high im getting 80psi at the fuel rail. I replaced the regulator with the same results anything would help thank you.
