Replacing a Fuel Pump on a 1997 Chevy Tahoe
The Chevrolet Tahoe is a full-size sport utility vehicle, or SUV, thats virtually identical to the GMC Yukon. A 1997 Chevrolet Tahoe most often has an 8-cylinder, 5.7-liter engine with 2-wheel or 4-wheel drive. This vehicle has sequential fuel injection, which requires a fuel pump that delivers fuel to the injectors at high pressure. The fuel pump in a 1997 Chevrolet Tahoe is in the fuel tank, so you must remove the fuel tank to replace the fuel pump.
Instructions
- 1
Disconnect the cable to the batterys negative terminal with a socket wrench. Loosen the filler cap on the fuel tank to relieve the pressure in the fuel tank. Drain the fuel tank by siphoning the fuel into a gasoline container with a hose. Raise the rear of the vehicle with a jack and support it on jack stands. Release the clamps on the hoses for the filler neck and vent tube of the fuel tank. Support the fuel tank with jack stands and detach the support straps for the fuel tank. Lower the fuel tank slightly and disconnect the electrical connections and hose on the fuel tank. Remove the fuel tank from the vehicle.
2Turn the retaining ring on the fuel sender assembly counterclockwise with tool J-39765. Remove the retaining ring. Lift the fuel sender assembly out of the fuel tank and pull the fuel pump into the attaching hose while holding the bottom support of the fuel pump in place. Discard the O-ring on the fuel tank.
3Install the new fuel pump into the attaching hose of the fuel sender assembly. Use care to avoid bending the fuel strainer since this will restrict fuel flow. Place a new O-ring on the fuel tank and install the fuel sender assembly into the fuel tank.
4Place the locking ring on the fuel sender assembly and turn it clockwise with tool J-39765 until the ring locks into place.
5Install the fuel tank by reversing step 1. Pressurize the fuel system by turning the ignition on for two seconds and turning it off for 10 seconds. Turn the ignition on and check the fuel lines for leaks.
