FrazerJames Posted July 30, 2020 Share Posted July 30, 2020 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. Anybody think it could be anything else? Link to comment Share on other sites More sharing options...

Gary Lewis Posted July 30, 2020 Share Posted July 30, 2020 Mean case of the bubbs. Yes, some place you are obviously getting air in. A hard line or maybe a bad connection between the rubber and hard lines? Link to comment Share on other sites More sharing options...

I think all my fittings are solid, but I’ll check again. Think I should try running nylon? Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted July 30, 2020 Share Posted July 30, 2020 Instead of hardline. I'd be very tempted to use the newer cupro/nickel brake line stuff. It's easy to form, obviously can handle pressure, won't corrode, you can solder whatever fittings you want on it and buy it by the foot at most auto parts. My truck came with nylon soft lines, but keep don't think I would use them to run up the frame rails. Link to comment Share on other sites More sharing options...

Just telling you where my head is going when I think of having to replace my hard lines. No matter what you choose, just be safe!

I’ll have to go get the Missouri safety inspection after anyway. I’ll make sure they check my work. Link to comment Share on other sites More sharing options...
