    Two questions:

    1) I have a small crack in my fuel tank. So small it leaks about 3 drops a day (so far). Anyone know a temperary fix just until I can replace. FYI its a diesel.

    2) Is a propane torch hot enought to melt the plastic injection on factory u-joints?

    Thanks!

    J-B weld makes a product that will dry even when it is wet or has fuel on it just for that reason. J-B weld is great :P

    There is gas tank repair epoxy...mix the two putties together and then spread it over the leak area. It will work if there is gas present at the time too. I think it's a Permatex product, but not sure on that.
    Yes, a propane torch will work fine to purge the plastic out of the d-shaft...that's what I used on mine. /forums/images/graemlins/thumb.gif

    I can't help you with the fuel tank but a propane torch is hot enough to get that nylon out... and it smells like poo.

    I had a leak in my diesel tank a few year ago, I just rubbed a bar of soap into the crack (the soap doesn't disolve very fast so it stops the leak for a while). Then I just cleaned it up with some solvent and a wire brush and epoxied a quarter over the hole. Worked great!! /forums/images/graemlins/cool.gif
