So I dropped the gas tank and took it to be cleaned,leak-tested and sealed. I've got it back now. The fuel pump was a mess, but I managed to separate it from the mounting hardware and cleaned that up so I can re-use it with a new fuel pump.

I have questions about the fuel gauge sending unit though. Does anyone know how to test it electrically to see if it's still good? It's not beautiful, but I managed to clean it up so that it will move freely. But before putting it back in (or deciding to replace it) I was wondering how I could test it to see if it's in working order. I didn't find anything in the FSM about this.
