After the $375 sticker shock of a new pump, I got a used pump and canister because the canister was shot too. If you can find a used pump that has been stored with fuel in the pump, it's probably fine. However if it's dry - chances are the thing is locked up tight as a drum and can't be easily repaired without a complete overhaul.
