Im wondering how often you guys change the fuel filter and is it something that can be done fairly easy... Ive heard some trucks have the filter in the tank.. is that true for the 03-07 5.9s ?
I dont own a cummins but from reading on here and from what a buddy of mines does its real easy. The filter is in the engine compartment. And he changes his every other oil change.
the reason I ask is from what Im used too, a fuel filter is usually changed every 15-30k... and Im right up next to 30k.. plus, lately it seems like my mileage is slowly getting a little worse (instead of better now that Im getting used to the smarty! lol)
the fuel filter is on the right side of the engine (when lookin from the front) put a pan under ur truck and turn the yellow knob to drain the fuel, then just wrench it off, pop the new one on, close the drain valve and ur good to go. takes less than 10 mins

Thanks guys... probably a question I should asked earlier! lol I think I will start doing it every oil change... now as far a filters.. wheres the best place to get em?
the dirtier the fuel filter gets the better it filters. install a gauge to the cp3 you will have about 7 psi only change the filter when the pressure drops to about 2 psi, at this point it is filtering twice as good as it did when new most of our equipment have gauges from the factory with red and green stripes on them to show when to change. we have 138 pieces that have diesel engines in them and a fleet of dodge's we do our own maintenance and some of our dodges are close or over 1,000,000 miles and some of the class 8 trucks have 3-4 million mile on them. both the fuel filter and air filter are to be changed this way.
Some could argue that 2 psi is a little low and could be doing more harm that way than any benifit that could be seen by running a dirty filter, which may filter better.

According to the manual the fuel filter should be changed every 15k miles. When I was running just my stock fuel filter I changed mine every 7,500 miles with a PF7977. A little over kill but injectors are not cheap. I get my filters from a local truck shop or from Cummins Northeast.
