Was in the HF store today and notice a red tagged 3 HP, 10 CFM pump out of the box w/ a broken air filter housing for $80 compared to $140 for same in the box. I'll check w/ HF parts to see what they want for a new filter housing. If they're too proud of it I'll build one Since the pump on my 25 yr old Craftsman seems to be getting tired I bought this one. I'll have to buy a v-style pulley for the motor to replace the serpentine pully and reroute some plumbing, but I don't think it will be a big project. I'll have to add some to the base but there wont be any welding done on the tank.
