no not that i have noticed but with all the oil from the vac pump all over the place its hard to tell. thats my next fix. have to call cummins and get the seal. from what ive read d/c will sell you a new pump but not the seal. what else is new lol scott

 

hey how much will it cost me to have you fix the kdp on my 96 before it becomes a problem?

 

Nothing but a bridge toll. PM or email me to set up a day and time that works for both of us.
