Engine/Transmission (1998.5 - 2002) What should fuel pressure be, has under hood gauge

[2shus]

I purchased this truck just a few weeks ago and am pretty unfamiliar with the 24 valve engine and pump setup, my previous cummins was a 12 valve. I am happy to have a cummins again and to renew my subscription to TDR. I have read that the lift pump or fuel pump from Dodge can go bad pretty easy and ruin the injector pump?? Please correct me if I got that wrong. Anyway this this truck has a fuel pressure gauge under the hood and I am wanting to find out what normal pressure is. It reads about 12 to 14 PSI at idle. Thanks.

That is right where it should be for a stock truck

It'll be hard to tell with the gage under the hood but from what I recall the LP psi should be no less than 10 psi at any throttle position so at 12 - 14 your IJ pump should remain happy, as the others mentioned with a stock unit. Welcome back!
