once I get my truck started it will run all day, after I sit for 10 minutes or ten hours, I lose my prime. I do see small bubbles appearing in my water and fuel separator more like small form bubbles. I know the fuel system is sucky air where do I begin, I did notice when I use the prime plunger and the main filter to prime the system it leaks fuel out of the plunger, in my opinion if it’s leaking fuel it’s sucking air.
Is there any other places where I should be looking, did replace the fuel pump still the same problem, next on my list is the main fuel filter assembly?
Any suggestions would be appreciated
