I'm not an expert on plastics but I would guess that if it is black, then it is ABS.

is the fitting in picture of same material? if so take a saw and trim a 1/8 inch cut off top and use for welding rod. Or try something like JB Weld or epoxy. Is crack where you can apply mechanical patch?

A friend in NC bought an plastic welder that uses hot air. The manual that came with it  had a chart showing the different symbols used on plastics to identify them. Are there any identifying symbols on the tank?  (I think they would be similar to the symbols on plastic bottles or plastic body parts on automobiles).  Jack
