I have an EDIC galaxy 300 psi model that I sort of inherited from a restoration co we work for. The pump is about shot, and I'm thinking of replacing the vac motors as well. I'm also thinking of rewiring the lead from the heater to power either the vac motors or the pump. Any thoughts (Willy) on how much redneck engineering it takes to do this? Will pretty much any pump/vacs off ebay work? I'd like to get as much power outta the thing as I can without heat...
