OK. I hope some of you are patient enough to read all of this. I changed my fuel filter a few weeks ago and the cap (factory fuel filter housing) was on super tight. I had to use a breaker bar to break it loose. The cap looked slightly cross threaded but I got it back on with new filter installed. I drove it a few miles and it died, after I noticed fuel all over the road. Towed it home, re-installed the cap. Had to crack the lines to get it started again but cranked right up after cracking one line. Went a few miles and after it heated up it died again. Cracked the fuel lines again, and again it cranked right up. Repeat process two more times, same result. I don't see any leaks now but Im still getting air in the lines somewhere. I have no check engine light or codes coming up.
So the question is could my lift pump be going bad, could the cap or filter housing be letting air leak in without fuel leaking out. I am on another forum and they kind of have me chasing my tail.
