the gas would melt any adhesive... cheaper to purchase a new one.

Answer 4

Whether it's the blower gas tank or the container to hold your spare gas, it's more cost-effective and safer to replace them.  As already mentioned, gasoline will dissolve most adhesives and the container will leak.  If it's the blower fuel tank, you really don't want gas leaking around a hot engine.  As for the storage container, you can pick one up at a big-box home center or garden dep't for a couple of bucks.
