So after reading through the first 6 pages of bull crap about facebook, wives, pumps other than AD's, and misc videos just to make sure I didn't ask the same question as someone else...screw, it. I don't care.
Anthony, do you find that the plastic brackets quiet down the pumps? It seems to me that they should help isolate the pump noise and help buffer some of it from the frame. I don't see a problem with a plastic bracket...as long as when they break, they are replaced free of charge. You could also press in some shouldered washers into the mounting holes. That would keep people from overtightening them. That way it would get tight and give them a warm fuzzy so they don't smash the crap out of it and disfigure it.
