Hey everyone, I just found out that I have a oil leak on my air compressor for my 2004 vectra with 350hp 8.3L isc and a leak on my fuel pump. I just drove it from Florida to Texas no issues and noticed a few drips of oil. I took to cummins and to repair both they want just shy of 10k. I have done some work in the past and wondering if anybody else changes one or both of these components. Thank you for your help
