Just because its colored black means nothing. Alpha Systems tanks are on many RVs. Theyre black and are not ABS, they're HDPE.

It's really easy to determine ... just wet the tank with Acetone and if it becomes sticky its ABS unless some other material dissolves like ABS to Acetone.

Even easier is to look at the connection where the 3" abs pipe connect to the tank. If its glued its abs, if its mechanically connected with a clamp, its probably HDPE.
Or look at the flange on the top where the tank hangs on the spreaders. If its flat and around 1/4" thick its abs. If its about 1" thick and is blow molded into the tank its HDPE.
The fact is if its HDPE it probably never cracked to beging with so its a moot point. Its a better material for a tank than abs.
