I was out yesterday and changed my fuel filter before the snow flies,well I found quite a bit of metal in the bottom,so I took it to the dealer and they checked the pressure and everything was good,the problem is I am right @ 100,000 miles and I am afraid the pump is going to go soon with all the metal that was in the canister,im about 400 miles from 100000.<br>Is the metal from the pump?<br>thanks..

Dave, do your self a favor and before you get to 100,000 miles check the fuel pressure yourself. I hate to bring out the nasty truth here, but the dealer is not dumb, 400 miles from end of warranty. You think you really got the truth??? If your pressures check out then I wonder how that stuff got past the filter as I would think that particles from the injection pump would be impossible. Could be wrong, It happened once...

Yeah I did that I have a fuel pressure gauge and I have about 15 PSI @ idle and that is what they got at the dealer.Is it the pump that is causing the metal shavings??

It is possible I suppose, I pulled my old pump apart and looked it over real good. It has 4 thick metal vanes that spin to push/pull the fuel up to the injection pump, they are covered with a wire mesh that is pretty fine and should I would think stop any particles from leaving the pump. At 15psi, if you have no abnormal noise from the pump that does not make good sense. I am confused at this point myself, I am real curious what other folks think it might be.

Perhaps burs from the metal fuel lines?<br>They weren't flushed properly from factory?<br><br>phox

I have been witness to several problems relating to this type of things in the new freightliners with the cummins engine. <br> The new fuel tanks are full of metal shavings. I don't know if they don't rinse them out properly of if they have them stacked near somebody using a grinder. But in the last 3 months I know of 5 out of 8 trucks deliverd new that way. perhaps Dodge has done the same thing with that tank inadvertantly. dropping the tank is a job but it just might be worth LQQking into!<br>

I found small pieces of metal ( alum ) in mine the first filter change but have never since.

Haven't found any in mine. Makes me want to go and check though.

I was told by a Cummins mechanic that it probably is not the pump,he said it was probably from when it was new,so he said to clean it which I did and drive it for a while and check it again,he don't think it was anything to worry about,I have great fuel pressure and the truck runs great,but I will keep you all posted..And thanks for the replys ;)

Heres an Idea.<br>Go to the dealer and ask to get that situation documented.<br>That ways if your pump goes out, you might be able to attribute the failure to the metal shavings that contaminated the pump (if they did) during the warranty period.<br><br>--Justin

Is this the first filter replacement?

I happened on this thread while looking for something else and thought that I would comment on it as I have in the past found where the metal chips come from and it also could have a bearing on the lift pump failures.<br><br>The chips come from the tank pickup slide in the tank. When changing my fuel sender I found that the slide had worn greately. At a later date I ran it quite low on fuel and the chips were picked up and run through the lift pump into the filter.<br><br>I locked the slide out of use on mine to stop the problem in the future. I have had no negative effects from the slide being bolted solid in the tank.

WHAT IS A SLIDE IN THE FUEL TANK??

I also had small pieces of what appear to be aluminum? metal burrs in the small ring shelf that seats up to the filter cap. There are small holes in this shelf and the burrs were almost all located on the firewall side of the ring. This caused me great concern because I had just changed my lift pump and thought that it may be shrapnel from the lift pump failure. My buddy that works for Dodge said that they were just what &quot;haulin in dixie&quot; said. The tank pickup slide is a very rough piece when installed new. The burrs work their way to the filter canister over time. Just remove them and they should not re-appear. When my fuel lever went out I did the same fix that &quot;haulin in dixie&quot; did and have seen no problems since then.
