Attention: TDR Forum Junkies Installed a new lift pump in february four thousand miles ago.
Pressure started fluctuating this weekend. Idle is 7 psi Rev the engine and it will raise sometimes to 12. Get her on the highway she will come up and hang in there at 11 psi with a 8,000 pound load behind me slow and stop pressure drops to 7 start out and press the accelerator as the rpms raise the pressure will also raise to about 11. Some times I would stop and it would idle at 14 but then drop to 6. Other times it bounces at an even pace from 8 to 12 psi. Was hoping the filter was pluged installed a new filter, no change. Im thinking I bought some dirty fuel, and the dirty fuel hurt the regulator in the pump? I bought the pump from hoesli diesel on the internet, Is there a warranty on these pumps?
44,000 miles on the rig. The way its acting I do not think it is my isolator, I do not own a portable test gauge to double check my hard mounted guage.
