Default Fuel pump connector under rear seat melting

My Classic broke down a few months ago due to the rear under seat connector getting hot and then the connection failing as it cooled down. The RAC man said the fuel pump circuit was drawing almost 9 amps which he thought was high. Local dealer didn't think so and couldn't offer much help other than trying new fuel filter or pump.

I have checked the connector regularly and it is continuing to overheat and melt so the connection will fail again at some point so what should I do? Can I just wire in a new connector block or do I need to be looking for the root cause of the overheating?

BTW - service from the RAC was excellent in tracing the original failure and getting the car going again

Any push-fit connector is only ever going to be as good as it's parts. The parts often get dirty, or corrode, some go loose, and all that results in high resistance. THEN the 9A you have found becomes a problem.

I would suggest taking it apart completely, both sides, after making a drawing, or taking a pic of what goes where. Use a thick needle or similar down the rear of the connectors to release them from the plastic. THOROUGHLY clean them, using first degreaser, then emery cloth or wet-or-dry, make sure the females are tight enough, but not TOO tight, then reassemble.

If it's gash, buy some new bits from www.vehiclewiring.co.uk, or similar, and start again, using SOLDER to fix wires to the connectors. You don't need the exact same connectors if starting from new, just ones that take the correct number of wires.

It's a known problem on Classics. You may find a thread or two about it if you do a search.
