Hey Yaw, I just joined this site and it is really great with lots of great information. Ive got an 04.5 2500 with 50000 miles and I have an oil leak that I believe is coming from the rear main and I also found fuel under what I would guess to be a fuel pump, Its on the drivers side under the intake and bolts to the front plate, Which pump is this? Also while its at the dealer will they perform TSB's at my request or only if Im having a problem? Thanks for any information.
