tank leak repair
BDI:
I've never seen any type of glue or epoxy that stuck to a plastic gas tank for very long. Not even the stuff that they claim is for it. The best luck I have had for repairing tanks is with plastic welding. I like to use an old fender, you can cut it into strips to be used as filler rod. Then you have the right color and the right plastic to make the repair. The down fall is that plastic welding is an art just like any other type of welding. When I do a tank repair with heat I like to fill it half way with water so if I want to cool the repair I can just role the tank over.

I too have used the plastic gas tank epoxy from an auto parts store with great results. Mine was the clear, not the black.

thanks BDI
i tried to plastic weld ,found out the whole bottom was cracked,while prepairing..
so i,m stuck with buying the sec-hand tank ,
just because i,m very afraid the tank will crack wide open.
with me sitting on it while doin a 70 mph straight ,
i don, t wanna think of it,a gallon of racegas sprayed over the very hot pipe & me legs
BDI:
If the tank has cracked like that it's probably brittle from age. Sounds like it has hit the end of it's life cycle to me.

I had a melted hole in a CR250 tank, from the exhaust being too close. I simply drilled a round hole at the leak , welded a flat washer to a carriage bolt, put a rubber washer on the bolt and fed it into the tank with a extendable magnet. Then on the outside I placed a rubber washer, then a flat washer, then a nut, I used a cutoff wheel to trim off the protruding threads. I did apply locktite first. This repair never, ever, leaked and as far as I know, the bike is still being used this way. Maybe next time, I would try a chrome washer and chrome acorn nut on the outside.
