Be sure to check all the associated wiring and terminals. A dirty terminal or one where the plastic has broken off, exposing a metal contact can cause a short. It shouldn't necessarily short out the fuse unless too much power is going to the pump. 20A fuse sounds correct, but I'd make sure (it should state in the owners manual which fuse should be in there). Electrical gremlins are the worst to have. Also, make sure all the connections are TIGHT. You can use electrical tape if you're suspicious that a connector might be the fault. It'll be a temp fix of course, but it'll get you to a shop that can properly diagnose.
