well after breaking the fuel petcock trying to get it tight to keep it from leeking and buying a new one, i then find out it is a tiny tiny crack in the tank. it is impossible to see if you dont put it over your head and look at the thing leak. I couldnt see the crack before i bought the new fuel valve cuz when it leeked the gas went to the fuel valve and dripped off of it. Now i need to repair the crack and was wondering if any ol fuel tank repair would work from wal-mart or car parts store. And remember 400ex guys 300exs have metal gas tanks. thanks for any advice.:confused:

i know there is some marine sealant that works awesome on polypropelene and plastic. a boating supply store should have it...i have used it but dont remember its name.

JB weld will work as long as you get it super clean first.
