[QUOTE="juanjuarez1509, post: 126498, member: 23203"] Hi all, I listened to all your suggestions and kept working at it. Thursday evening I received all the parts I ordered but I wasn't convinced that swapping them all in would cure the problem. I pulled the lift pump to test it. I moved the hose that jumps to the injector pump into the inlet. I tested the pump and was squirting but would pick up air sometimes. I repositioned the hose then it started squirting like I believe it should. I replaced the line and put a clear inline filter to see what was happening. At that point, I could see that now fuel was flowing and air was no longer being trapped. And what do you know, she fired right up and ran better than ever. Long story short, it had a lot of problems, up to and including the fuel lines themselves being faulty. Full list of things done/replaced: Removed fuel tank, emptied, cleaned out of all junk(there was a lot) replaced the pickup tube with the one way filter and reinstalled. Cleaned all the fuel lines with compressed air and reinstalled. Did not replace. Replaced the fuel filter with a Wix filter Replaced the primer bulb Primed the system with the bulb to the filter valve Primed the system with the bulb to the bleeder valve on the pump replaced fuel lines themselves It has now ran for 10 hours without dying and any issues.
