Air leak.
 

Ok guys on my 01 2500 I have acquired an air leak that is letting the system loose prime when it sits. Only takes about 30 min to do this. I've replaced o ring washers on feed side line, and on the return side at the banjo bolts. Also replaced the T fitting and gaskets. Replaced the fuel bowl drain, and the entire return line. All injector lines are good, and no sign of diesel in oil for crossover tubes. Now when I did the T and the return line it had no issues for about 24hrs. Then it came back so I went through and checked everything again today. No signs of leaks or faulty connections. Anybody have some ideas?? Because I'm all out.

have you tried the check valve on the vp?

Have you replaced the orings on the tubes?

I've replaced o rings on everything lol. And yes check valve on VP is good. I'm about 99% sure it's the banjo at back of the head. It keeps backing out.
