Definitely food for thought. Here's my thought process: Either I vapor locked, the fuel filter clogged, or the fuel pump is going bad. I didn't have any issues until after I stopped and filled the tank up. The 9 month old gas ran through OK. I'm also thinking since that upper line didn't have any fuel in it, the problem occurred somewhere before that point.
Just out of curiosity, is the diaphragm in the fuel pump made out of rubber as well?
At any rate, the fuel pump, some new rubber lines, and a new filter aren't that expensive. Just have to find the time to take care of all of that.
