FWIW my truck is completely stock down to the air filter. '02 QC HO with 26,000 miles on it. I noticed a slight drop in pressure last week so I replaced the fuel filter. The pressure continued to slowly drop after that and is now 10 psi at idle, 8 psi cruising the highway and it will go to 0 if I go WO up a hill.
The Dodge dealer in Red Wing is replacing the lift pump today under warranty. Immediately they didn't like the fact that I had no other problems other than the low pressures but once I told the service manager that I had noticed a pressure drop over the past week and I could get it to 0 at full throttle he was more than happy to replace it.
