Just because its colored black means nothing. Alpha Systems tanks are on many RVs. They're black and are not ABS, they're HDPE. You cna attempt to glue, flexseal, or essentially cobble together a repair, but if the tank is blow molded HDPE the only permanent solutions that can be counted on 100% are either new tank or plastic welding.
