The best thing to do is disassemble it and clean it out, as well as draining the old scuzzy gas from your tank, replacing the filter, and cleaning the strainer. The pump is most likely still good if it gets hot - this means that it hasn't blown out YET, but it's siezed in one position and WILL burn out if power is applied to it too much. If it is siezed, it's probably because of the 12 y/o gas broke down into crud, which settled in the bottom of the tank, and stopped up the fuel pump (and possibly the filter and strainer and injectors). Clean it, bench-test it to make sure it runs (it should, use only 12 volts DC, and make sure you get the polarity right).
