I need a new fuel filter/canister cap but noone I call can look one up without a part number. I need this thing tonight so I can get to work in the morning but the only parts departments open are for big trucks. There is a number on the cap which is 3892545 but it doesn't cross-reference to anything. Can anyone give me a cummins part number for the cap? The truck is 2000 by the way.

 

It took trips to three different Dodge dealers and a half a day of work missed but I finally found one. I no longer need the part number.
