Okay, obviously a fuel leak, but what's under there to leak?? Is it the actual tank leaking?

Don't know what it is (YJ, TJ?), but my YJ fuel line fittings started leaking after I dropped the tank to fix the smashed skid. I just tightened them up and it stopped.

If it's your lucky day, on of the fittings on top of the tank started leaking and is running down the strap, if it's not your lucky day, the strap wore a hole in the tank. Mine would only leak when it was running, but leak way bad, turned out to be a pinhole in the fuel line. When I turned the key on with the tank dropped, a tiny stream of gas shot all the way across the garage from just a barely visible nick on the hose.

Yeah, it's a YJ. Guess I'll be in the market for a new tank. Any kind of tank better than others. I've never looked at them before...

Well, it only leaks when it's running, therefore when there's pressure, so maybe it is just a line in there somewhere. I'll have to drop it down and have a peak.

Thanks!

Yup, same thing mine did, only leak while it was running, so it might be your lucky day after all, have fun dropping the tank, it's a bitch, especially if your exhaust is in the way.

Mine did it too. Directly above where your pic is there are a set of fuel lines with clamps on them. TIGHTEN THEM ;)

That's what I though when mine started leaking, I had just re-installe the tank after fabbing my new rear bumper, I thought my lines were just lose, so I dropped it, tightened, re-installed, still leaking while running, so I dropped it again (ARGH!) and turned the key on, I walked around and could smell gas like a mofo but couldn't see the stream until my leg started getting wet. Good thing I don't smoke! It turned out to be a pin-hole where I had clamped the line closed to remove the tank.

Huh. Mine was just those clamps loose :shrug:

I am running a trailquest 26 gallon tank.

Not sure I would do it again.

I got this problem too, I pulled out my tank to fix a pinhole leak, I put everything back together and crank it up real tight, and when the motor is on, it spews out of the sending unit area, if I loosen the bolts and let the tank hang down a few inches, it doesn't leak. Some how, now that I put the tank back in where it was before for many friggin years, it starts leaking at the top now. How could I have mounted it higher than it was before to put pressure on something up there and cause it to leak?:shaking:
First my axle blows up now this.

This happen to any one else? I'm thinking may be the sending unit seal, but looked fine when I had everything out and cleaned it up.
Sorry to bring up an old thread, I was serching.
