Electronic Goldmine - Large 12VDC 60PSI Boat Washdown Pump 03501-136
Could be used as a spare or stand alone to wash toys.
I have two of these from electronic goldmine, mine are debadged but they are the same pump.
If one is interested, get on the mailing list and wait until the price drops. It'll go down in a few months. I think the last one I bought from them was 12 bucks or so, no label and still unused.
Just FYI, a pressure switch in the demand pumps cost nearly 30 bucks should one need a switch. Whole pump or switch, hmmmmmmmmmmmmm
