i managed to round up a bracket, glass bottle, and pump.Still looking for the foot-pedal part. Anyway, the lid on the bottle has a port that says "water" - which looks like the output to the spray nozzles - and a rusted/worn away marking on another hose connection that might say "vacuum". i sort of expected air pressure to be connected to that port so it would force water to be pumped out, but i guess vacuum could be used to run a pumping mechanism as well. So, what connects to this port? An air pump or manifold vacuum? thank you.
