I’ve used epoxy like JB Weld on many plastic things, but you have to use files and/or sandpaper to roughen up the immediate adhering surfaces so the compound can get a grip. Since Jeff’s issue is at the tank bottom and under fluid weight pressure, he will want to empty the tank to apply and let the epoxy cure. The rougher the surface and the broader and thicker the coverage, the better.
Another thing I’ve tried with some success recently is a product found at my Ace Hardware in the glue section. It’s a gritty fine powder in a small squeeze bottle called “Johnny Weld”. You squeeze/spread super glue on the cracked area of a broken object and pour the Johnny Weld on it. It solidifies immediately. You can drip more super glue on that and add Johnny Weld to build up your patch. It’s not permanent but may get you to a repair shop. I discovered not to use gel type super glues, just liquid, and prefer Loctite’s “Professional Liquid” in the 0.7 oz. blue bottle.
I often squeeze superglue into a crack to help stabilize it, or fasten 2 pieces back together, before applying either epoxy or JWeld over the break.
There is a learning curve with this, like its best to roughen the adherent area well so the mix gets a grip, just like with epoxy. Otherwise polyethylene is a really tough stick for any glue. You don’t have to wait long for the Johnny Weld to set up like you do with epoxy, and there’s no mixing ahead of application.
