I replaced the filter on the truck in my signature. I bought the truck on 4/28/07 and finally go around to changing it.

The filter came out black as sin. It was filthy. I put the filter housing in my parts washer because there was a black film on the inside walls of the canister.

Do your filters come out black? I wouldn't think they woudl be that bad.

BTW the truck idle is smooth and I have more power and black smoke.

 

yep, mine come out black, change your pre-filter also?

Most all diesel filters come out black.
It's due to asphaltines that are present in all diesel fuel to varing degree.

Wear is that filter located?

You can get a pre-filter kit from Cummins for $8.00. It gives you a new screen , nut, and a gasket. When I just did mine I noticed the upper gasket on the pre-filter/heater assembly was dry rotted. You have to get another gasket from them (cummins).

 

What are the Cummins part #s for the pre-filter kit and gasket?
