So I bought this truck recently but there's a problem that it leaks fuel from both tank lines at the very top of them just after the fuel doors.
The first picture shows where it's leaking, right at that band clamp. And the disconnected hose in the second picture I have no idea what it is supposed to be hooked up to. Or maybe it's not important? I've been driving it with no trouble so far
I bet you'll find rust pin-holes behind that clamp. Happened with two of my filler pipes. Metal on metal.... I don't weld, so I took it to my buddy down the street who does. He suggested I try some epoxy type sealer/filler. I found some of this stuff - PC Epoxy - at Ace Hardware. Just got the little size, two little plastic cans (if you ever did 35mm photography, I swear they're using all the old Kodak film cans).
The components are a thick pasty consistency, similar to spackling clay, one gray one black. You know you've got 'em completely mixed when the result is dark gray with no streaks/swirls. Spreads on with a wooden stick. I cleaned up all the rust, slathered this stuff over the pin-holes, let it dry, then I put a piece of bicycle innertube around the pipe where the clamp goes around it, so it's no longer metal on metal. They've been bone dry ever since.
I saw one fella put a little chainsaw fuel filter on the end of that axle vent hose. Whatever you do, don't let it get clogged.
