North central TX | Dad's 7220 has had an intermittent issue where it was losing prime and failing to start unless he cracked the injector lines and bled them then it would run fine and might not act up for a while again. Recently we went to start it and it started and died almost immediately. He was able to bleed and get it running again and baled 20 acres and it started the next time but since parking it back over near my house it won't again bo matter how much bleeding. Hes given up and I've taken over for the time being. I thought it may have a supply line leak but don't find any leaks and can blow air into the line and get bubbles in the tank and get good clean fuel out when blowing on the tank. The pump is working, running full time, which he doesn't think it used to and I don't see bubbles coming out of it. I have pulled the supply line loose to the injection pump and seem to have a good supply of fuel there.
Edit to add pic and that it has 4060 hrs
What's next? Thanks
