The ones we cut were thin wall tube, much like exhaust tubing, if I remember correctly. I do remember that we couldn't just cut it off and stick a hose on it because it was too low, we had to make a couple cuts and make a sort of "z" shaped neck to clear things on the bottom hose connection. At the top I think we were able to cut it and put a hose on it. Also seemed to remember the hose necks were were a large diameter, near 2", I think. It was a few years ago. Gene
