Hey guys, I wouldn't say I'm not too "new" but this is my first post. My name's Curtis and I live in the Charlotte area of North Carolina. My truck is a 2002 24v auto. At 239k miles, my truck definitely has some developed character. I'm still learning all the quirks and nuances that comes from third-hand ownership and many miles. The end goal is a beasty daily sleeper.  My most immediate concern is getting my fuel pressure up. I just installed some glowshift gauges and my FP is 6.5psi at idle and 3-4psi at a steady 2k rpm. I plan to put the stock banjo bolt back in and check to make sure its not the glowshift sensor. Anywho, I'll be seeing you.

Welcome from Hickory NC. That fuel pressure is concerning. It most likely will read 0 at WOT. It would be best to get test gauge to double check the pressure. Are you running on the oe style pump and fuel lines?

Thank you, Dripley. I haven't read any pressures below 3 as of now. I changed my fuel filter today and got a 1 pound bump up. My current setup is the oe in-tank retrofit with stock lines.

what pressure do you see when stick your foot in it? If its 3 cruising I bet its 0 at wide open throttle, WOT. I got the intank pump at 150k and inside of a year I was seeing the pressures you are seeing now. Not good. I would recommend a full Air dog or FASS or a mechanical pump with new fuel lines. The stock lines are too restrictive to maintain adequate supply to the VP.  Anything that will keep your pressure up to at least 14 psi under any condition. The oe fuel system is inadequate and will cause premature VP failures. At $1100 a pop you dont want that to happen.

I attempted to bottom out my FP but couldn't get a long enough stretch on I-85 to get it to drop below 5psi now that I've changed my filter. The plan is underway now to replace the fuel system. Wish I discovered this sooner when it was warm out.

I did not find out about all of this fuel pressure stuff until about year after paying a Dodge dealer around $900 for the intank set up. It only cost about $700 for me to replace the whole system plus my time.
