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.

Its inverted flare. You can swap it with hydraulic line. Remove the fitting from the block on the engine. Its inverted flare as well but you need the inverted flare 1/4" to #4 male jic. Jj performance llc on Elmore rd is the only place that will have it.

Pump end is also inverted flare. Pump side is 1/8" boss. Typical hydraulic swap is boss to #4 jic male. And a short hose

I've got everything on my table at home you need
