Hi all, I just purchased a 1994 Peterbilt with an all original non electronic 855 N 14 Cummins engine that uses the PT system from a local shop.The problem with the truck is that the entire fi system left with the mechanic.no pump,lines, injectors. Since the injectors are already out, I want to do a compression check to see if there are any other problems before investing in the parts. What type of compression guage do l need to do this?
Compression check how to, 1994 Peterbilt w Cummins 855/n14
