Does any one know what sizes and types the tube and fittings are on the return line that connects to the pt pump? This is on a M818, NHC-250 Cummins.
I was mounting my rebuilt pump and when I was tightening the return line, I never felt it get tight, or even snug. Then I notice the fitting was cracking. I just don't think the fitting will hold now. Sorry about the blurry pic, but the crack is visible in the middle of the fitting.
