I did.

My system is a tad 'special' due to my WVO conversion (that has been in place for 3 yrs / 40k+). The lift pump is plumbed after the secondary filter (as opposed to before it), so that assembly is under vacuum as opposed to pressure.

My priming procedure involves loosening the bolt at the inlet to the IP since that the easiest place for me to access that's under pressure. I then pump until I feel that I have gotten the air out (and spilled diesel all over the ground) and then close the bolt and pump until I hear the 'buzz' sound from the IP indicating prime.

My question really revolves around if the engine goes on a 50 mile trip just fine, and then has air upon restart, does that definitively indicate an air leak?
