JB Weld should defenitly be sufficient and will hold up to gasoline. Another product you might try would be gas tank repair. It's pretty much the same concept as JB although either one will work fine. Just make sure to clean surface of crack.
I work in a small engine shop and we repair old plastic tank all the time with an ELECTRIC soldering iron. Just melt the crack back together. It works great. You can even use trimmer line as a filler if needed.
alright, I've got "gas tank repair" smudged into the crack/s and then smothered all over it to cover them up. Then I've got JB weld smothered all over the top of that crap (all topped over the hot melt glue base that didn't work). I've got the throttle cable electrical taped so the cable housing won't slide and the trigger will work good. Now all I have to do is restring it, and I'm good to go with a second trimmer. I should probably put a new spark plug in it. It's sparking blue instead of white. What do you think?? hehehehe

Marine Epoxy is impervious to gasoline, I have repaired metal gas tanks and it has not failed. Plus you can repair your canoe while you are at it.
