If you’re following along, just got a bronco that sat for 12 years. The owner replaced the old rubber fuel lines but it was still having fuel delivery issues. This past weekend I replaced the fuel tank because it was downright nasty in there. There was no savaging it. While I was at it I replaced the fuel sender and inspected the fuel filler neck. All looked good.
For the big finish I go to start the truck and she starts right up. Then she stalls. I checked the clear pre filter on the fuel line and very little gas is in it. Just to be sure everything was working after the filter, I ran the fuel filter line directly to a gas can in the bay. Started right up and stayed running with no problems. It’s gotta be the hard line.
To be sure I hooked up my mighty vac to the prefilter going back to the tank. Just one squeeze and the filter filled up. And then... bubbles. Consistent good size bubbles. I have an air crack in the hard line I believe.
