In my experience in custom airbrushing, due to the way the pumps move the air they dont create a substantial vacum on thier own. Idk about the first pumps but I know if i try using mine to suck it heats up fast.[/quote]
I would NOT recommend hooking your pumps in reverse, due to the fact they were never built to work that way. (otherwise there would not need to be a resona to color-code the wires

)
