    I have a 2-stroke motor on my bike with the two fuel lines going into the plastic tank. Lately I've been getting a lot of leakage where the fuel lines come out of the tank.
    I tried silicone sealant, but it disintegrated with contact to gas after one day.
    I think epoxy is gas-resistant, but I don't know if I want to epoxy my fuel lines into my tank.
    Is there a flexible sealant that is gas-resistant?

    If you want to go with your original plan of fuel-resistant, flexible glue... most auto parts stores will carry this stuff called "Seal-All" that is made by the same people who make Goop. My friend used it on one of his fuel lines that were cut, and it worked... but as soon as he bumped the fuel line against something, the glue was ripped off. Seal-All works best on metal gas tanks and such, and doesn't bond too well with shiny plastics like these fuel lines.

    There's also Rector Seal No. 7, which you should be able to find at a plumbing store / hardware dept. Beware, this putty costs close to $40.

    vinyl tubing, like fish tank air hose, works great as fuel line. just replace it or it will break at the most inopertune time
