Fixing a baja gas tank

Hey everyone, I have a crf450x that I made street legal to rip around Salt Lake City. I have a baja tank that the owner gave to me, but it has a small hole (nickel size) where one of the brackets got over tightened and cracked. I tried a gas tank repair kit from Advanced Automotive but it couldn’t handle the change in temperature in the city and didn’t hold. Wondering if anyone has any suggestions on a fix for this, don't want to scrap the tank if I don’t have too. Thanks

I've used 2 part jbweld (They have lots of options) on a steel gas tank with pin hole leaks and it's worked great for 2 years.


But having a nickel size piece missing in a plastic tank is obviously a way different problem.


IMO - You basically need patch the hole and not sure if care what it looks like.  Think finding a similar type of plastic to the tank, then gas resident adhesive for the type of plastic, proper prepping and curing.


Someone else maybe able to be a bit more specific.


Or my go to or some other variation


Good luck

Not gonna work


Your plastic tank has 'outgassed' to the end of it's life, and is no longer pliable.


Gotta get a new one.
