RPMDodge,
I got mine at Cummins West in West Sacramento. It was a Fleetguard part number #CV50115 for Dodge 5. 9L Cummins engine applications. I'll be the first to admit it was kind of pricey at $242. 44 out the door, but if I had to do it again I would. The hardest part of the install was pulling the front dipstick application soft plug out of the block to install the oil return line. The method I used worked for me and I had the whole thing installed in about 30 minutes. PM me if you you need any help.
Regards, Mike.
