My fuel return line is dripping where it transitions from hard lines to braided lines and into the cooler. Both of the fittings are pretty rusted.

Is there a quick fix?

Do they sell just the braided lines?

I'm stranded at work.

Alright,

I cut off the fuel hard return lines and cut off the quick disconnects

Used 5/16" hose and hose clamps.

Will it's hold? I'll take pics

I would think it would temporarily until you could get a new cooler put on it. You could also bypass the the cooler with a section of hose and a couple barbed fittings for a quick get it home fix.

I know a few northerners that had to temp. bypass theirs because of rusting parts.

Nice temp job, could always put an extra clamp on for security sake.

PS: damn thats a dirty cooler:D

Yeaahhh......she's a little dirty and rusty lol

The leak was actually a Pinhole in the hard line that runs back from the cooler to the tank.

And I did put 2 hose clamps on the cooler - tank line ends!

The fuel lines are very low to NO pressure, because that is un-used engine fuel returning back into the fuel tank.

i thought crap didnt rust in the south?? anyways, what you did will work for a while. the quick connects you cut out serve no purpose than a quick easy way for the factory to build the truck. up here in ny, where rust is everywhere, i make new fittings that go into the cooler. i have a hydraulic flaring kit that has die's to make the flared ends it needs. then i run plastic fuel line and plastic quick connect fittings. never rusts out again! if the customer doesnt wanna buck up for that repair, i make the same stub lines out of the cooler but put a slight bubble flare on the end to help hold the rubber hose i clamp on.
