I have a 2002 Dodge Ram with approx. 50,000 miles on it. It seems like I've lost a little power on the top end, like when I'm attempting to pass someone, and also on the bottom end during hard acceleration. Could the fuel filter be the culprit? Other than the slight loss in power, the engine runs very smoothly, without any noticable misses or stutters. Any help will be very much appreciated. :help:

It could very well be that your fuel filter is plugging. Are you down on mileage as well? It would also pay to check the air filter too.

Change the Fuel filter and check lift pump pressure.

I have a 2002 diesel as well, with 12k on it. When and how do I change the filter. I have changed the oil 3 times now and that isn't too bad. I baby my engines and try keep them as clean as possible, so they will last.
Thanks in advance.

The biggest issue with these fuel systems is lift pump pressure. When the pressure from the lift pump declines, the injection pump will soon follow (fail). The IJ pump need lots of diesel fuel circulating through it to be kept cool. Run a fuel gauge to monitor lift pump pressure.

Also check your air filter.............

To change the fuel pump is easy. Open the drain valve and drain all the diesel fuel out of the housing. This may require you to turn on the key for a few seconds and let the lift pump pressurize the housing. Use a 1 1/8" socket to remove the filter lid. Discard the filter that is snapped into the lid and replace with a new Fleetguard filter. Oil the new rubber O-ring that comes with the filter and replace the old O-ring around the lid. With a lint-free cloth, wipe out the inside of the filter housing. Put the filter and lid back on and tighten down until snug. Turn the key on and let the lift pump rund for about 30 seconds to prime the filter housing. Then start the truck and check for leaks.

I'm new to the forum and did a search as I'm about to change my fuel filter for the first time on my 04 Cummins. Got a few conflicting reads and wanted to make sure this is the correct procedure...particularly how to prime the housing. I have an old Toyota Landcruiser diesel and I know when you change the FF in it there was an old school hand pump to prime it. Does the above quote give an accurate descp? Are there any other "tricks" I shouold know about it? BTW, the dealer wanted $321 for a 15k service which as far as I can see consists of an oil chng, FF chng and drain the axles....what a rip!
Thanks in advance... :D

I did it just like breakin loose said except I primed mine 3 times, turn the key let it prime, turn it off, turn the key, let it prime, turn it off, did it 3 times then start it. This is what the cummins shop told me to do. I didnt drain all my fuel out though, I did drain some but not all. I cant believe how much the dealer wants for a fuel filter change, 60 bucks I think. Its a 13 dollar part and 15 minute change. What a rippoff.

when you remove old filter, note where fuel level is before you drain it. drain it and replace filter and gasket on housing lid. then, take some fresh diesel and fill housing to level it was before, or a little more if you dont mind a little spillage. then replace lid and filter (slowly to allow fuel to soak and fill filter and not run over), then fire it up after cleaning any spill. this way there is no air to bleed. just my .02.
