I have been having problems with my fuel pump on my 90 GT. I dropped the tank for the forth time in two weeks & and went through three fuel pumps. This time I noticed the red connector that attaches to the top of the fuel pump hanger assembly was burnt through exposing the electrical connection. I further examined the hanger assembly itself and the top where the electrical connections connect was melted a little. So I had to buy a new fuel pump hanger assembly and red electrical connector from the ford dealer. I was wondering what could cause this to melt on both electrical connections. The only other recent problems I had was two months ago & it was the alternator and its connection wires. The previous owner didn't have the electrical connection to plug into the alternator so he soldered the wires to the alternator. I got a new electrical connection for the alternator. But I might have mixed up the wires on the two thick black & orange wires when I was connecting them to the new plug. Could this be the cause of the burnt electrical connections on the fuel pump hanger assembly? Any info/input greatly appreciated.
