    So, my 78' has a leak at the filler tube, thankfully it's only a problem after a fill-up. Looks to be leaking where the filler tube meets the tank. Is there a grommet or seal? On all the re-pop replacement tanks I've seen, its welded, but mine doesn't look to be...

    I had the same problem on my 70. Would stink up the garage with a full tank. No seal on mine where the tube met the tank. I just replaced the tank.

    Huh. Dangit. Guess mine broke at some point. Looks like new tank it is.

    Drain the tank and take it to a radiator shop. It was originally soldered at that point, and any good shop can resolder it for you if the tank is still in good shape.

    Either replace the tank or have it fixed. My daily driver did the same thing a few days ago. I can't have fumes leaking out so I wire bushed it with a brass brush, brake cleaned it and slapped red rtv on the seeping area. No fumes no leaks for the moment. I'll be replacing the tank over the weekend.
