Solid tank, not thin walled like some are.
Bought this as a replacement tank for a commercial mower. I wasn't about to spend $66.00 at the dealer for a plastic tank. Was not a direct fit, but I made it work with two new drilled holes and some self tap screws. Works like a charm. The hose hookup is on the bottom, I blocked it off and drilled a hole on top so I could us the old hose setup. It does the job.
