How to Change the Fuel Pump in a 1995 Mercury Sable

The Mercury Sable was a mid-size upscale sedan manufactured by the Ford Motor Company from the 1986 to the 2005 model years. The Sable is very similar to the Ford Taurus, with only a few cosmetic differences distinguishing the two models. The 1995 Mercury Sable came with a base 6-cylinder 3.0L engine or an optional 6-cylinder 3.8L engine, each with electronic fuel injection and a high-pressure electric fuel pump. Changing a malfunctioning fuel pump in this vehicle is a fairly difficult task that requires some expertise and specialized tools.

Instructions

1

Disconnect the negative terminal of the Sables battery with a socket wrench. Relieve the pressure in the fuel system. Pump the fuel out of the fuel tank through the filler neck with adapter hose 034-00011 and rotunda fuel storage tanker 034-00002.

2

Raise the vehicle on jack stands and remove the filler tube for the fuel tank. Support the fuel tank, and disconnect the support straps for the fuel tank. Disconnect the fuel lines, vent lines and electrical connectors from the fuel tank. Disconnect the fuel tank.

3

Clean the area around the attaching fuel pumps attaching flange on the fuel tank with a shop rag. Turn the lock ring for the fuel pump counter-clockwise with fuel tank sender wrench D84P-9275-A, and remove the lock ring. Disconnect the fuel pump assembly from the fuel tank, and remove the gasket from the attaching flange on the fuel tank.

4

Clean the mounting surfaces on the fuel tank. Apply a thin layer of grease to the new gasket, and place it into the fuel ring groove of the fuel tank. Place the fuel pump assembly into position without damaging the fuel filter. Replace the lock ring so that the locking tabs on the lock ring are under the tabs on the fuel tank. Turn the lock ring clockwise with fuel tank sender wrench D84P-9275-A until the lock ring reaches the limit of its travel.

5

Install the fuel tank and connect the fuel lines, vent lines and electrical connection for the fuel tank. Lower the vehicle and install the filler tube. Add 10 gallons of fuel to the fuel tank, and check the fuel system for leaks. Connect the cable to the negative terminal of the battery.

6

Attach a fuel pressure gauge. Turn the ignition on for three seconds, and repeat this procedure at least five times to pressurize the fuel system to at least 30 pounds per square inch. Check the fuel system for leaks and disconnect the pressure gauge. Start the vehicle and check for leaks once again.
