If I had a crack I the tank, I would probably try fixing it with an Eternabond patch
Or maybe
A big patch of FlexSeal patch tape

I had a big crack in a potable water tank & had it welded at a plastic shop. It was caused by my own stupidity. I left the hose running in the fill port & lost track - boom! As I said it was a nasty crack/break, but the repair was only $150.
I would not use Eternabond or FlexSeal tape. The non-curing adhesive will be exposed to your drinking water & I doubt very much that it is food safe.
