What owners wrote
Fuel leakage occurred due to the brake line rubbing against the fuel tank which also caused the gas tank to corrode. Dealer installed the new brake line it also hit the gas tank.
I have pictures of the fuel pump I took out of my 1992 mercury grand marquis. The car had coughed to a stop and I suspected the fuel pump. There was no pressure in the fuel rail so I pulled the pump out of the tank. I checked the pump with a battery and it ran fine. Then I started looking at the fuses and found the 20a pump fuse blown. Obviously there was a short somewhere. As you can see by pic 2 the short occurred when the "hot" wire insulation was worn through on the float bracket.
