If so, a used one or a new one should be that much. most Mitsy parts are pretty reasonable.

Try to connect that hose to another one that is in some water ( like a water jug, etc..

If you don't hear the pump, the fuse might be blown or missing.

It's a pretty simple set up once you confirm the electrical stuff is still in place and working.
