So I'm having this problem, every 10-15 hours my engine will die. I pop the bleed screws on the fuel filters and it is pressurized with air. Bleed it out and it runs fine for another period of time, as bad as 2 hours but usually 10 or so. So I replaced the racor filter and seals, the fuel filters and seals, the seals that go into and out of the filter housings, and I still have the same issue. I found that my lift pump housing was cracked, figured that was the problem so replaced it. Nope, same issue.......This engines (2725e) fuel return line does not go back to the fuel tank, it goes, uh, somewhere else, not sure exactly, guess it just loops back around and tries again, for lack of understanding. Anyway I take that line off after the injection manifold and I have air in that line too. So I'm just not sure where to look for this air leak at this point. Was hoping someone had been thru a similar senario and could point me in a direction to explore. My next option would probably be to replace the racor unit, I did drop it once, but it does not leak fuel so... I can get the engine running in less than 2 minutes, but if it ever happened while I was docking, well, that would be very bad. Ideas?
