How to Remove the Fuel Pump in a 1996 GMC Yukon
- 1). Disconnect the negative battery terminal with a socket wrench to prevent the unintentional discharge of fuel. Open the fuel tank's filler cap to relieve the pressure in the fuel tank. Siphon as much fuel from the fuel tank as possible with a hose. Drain the fuel into a gasoline container.
- 2). Raise the vehicle with a floor jack and support it on jack stands. Disconnect the filler neck and fuel vent tube from the fuel tank. Support the fuel tank with a transmission jack and remove the support straps for the fuel tank with a socket wrench.
- 3). Lower the fuel tank slightly with the transmission jack so you can disconnect the electrical wiring and fuel hoses to the fuel tank. Disconnect the fuel tank from the vehicle and move it to a work area.
- 4). Turn the locking ring on the fuel pump assembly counterclockwise with a hammer and brass punch. Remove the locking ring and pull the fuel pump assembly from the fuel tank. Detach the fuel pump from the rest of the fuel pump assembly.
- 5). Pull the fuel pump away from its bottom support without damaging the rubber insulator or fuel strainer. Pull the fuel pump out of the rubber connector after it is clear of the bottom support.
