I replied to this earlier but my reply didn't go through?

If your '91 is like my '87 then the relay is the protective device between the battery and the pump. If the relay is melting then chances are the circuit is drawing too much current (ie the fuel pump motor is going bad). In this case it is not a good idea to jumper it.

If you do jumper it, put a fuse in line with the jumper. Say 20 or 30 amps max.

On the plus side, if your '91 is like my '87, then the fuel pump is very easy to replace.

I've never had to remove the socket so I'm sorry but I'm of no help with regards to where the wires go.
