How to Replace the Fuel Pump On a 96 Blazer
The Chevrolet Blazer is a mid-sized sport utility vehicle made by General Motors and it is very similar to the GMC Jimmy. The 1996 Blazer has a 4.3-liter 6-cylinder engine with sequential fuel injection. The electric pump in the 1996 Chevrolet Blazer attaches to the fuel sending unit in the fuel tank. It is, therefore, necessary to remove the fuel tank when replacing the fuel pump in this vehicle.

Turn off the engine for 10 minutes to allow the fuel system to depressurize. Disconnect the negative terminal on the battery with a socket wrench to prevent accidental sparking while you work on the vehicle. Loosen the filler cap for the fuel tank to relieve the pressure in the fuel tank.
2Siphon the fuel in the fuel tank into a gasoline container. Raise the vehicle and support it on jack stands. Release the retaining clamp for the filler hose on the fuel tank and disconnect the filler hose.
3Support the the fuel tank with a floor jack. Remove the fuel tank straps with a socket wrench. Lower the fuel tank slightly so you can remove the fuel lines and electrical connections for the fuel sending unit. Lower the fuel tank completely and move it to a work area.
4Turn the cam locking ring for the fuel sending unit counterclockwise with GM tool No. J-24187. Remove the cam locking ring and lift the fuel sending unit from the fuel tank. Pull the fuel pump away from its bottom support, and then pull it into its mounting tube. Use care not to damage the insulator or fuel strainer.
5Install the new fuel pump by performing Steps 2 to 4 in reverse order. Tighten the nuts on the fuel tanks retaining strap to 33 feet/lbs. with a torque wrench. Connect the cable for the negative terminal on the battery with a socket range and correct any fuel leaks.
