The base model of the 1988 Oldsmobile Toronado included a 3.8 liter six cylinder engine. It had a manufacturer's suggested retail price of $20,598, produced 165 horsepower and 220 foot-pounds of torque. The Toronado also came equipped with an electric fuel pump that was installed inside the gasoline tank of the vehicle. The fuel pump pulls fuel from the gas tank and sends it through the fuel lines of the vehicle. It is important to know how to properly change the fuel pump to avoid damaging the vehicle's fuel system.
Tools Used: Pliers, Wrench, Siphon, Gas can, Funnel, Wheel blocks, Jacks, Jack stands, Socket wrench, Hammer, Brass punch, Towels
Change a Fuel Pump
Prepare the Vehicle
Detach the battery cables from the battery using some pliers and a wrench. Remove the fuel tank cap to relieve the pressure inside the vehicle's fuel system. Siphon out as much of the gas as possible into a gas can with a funnel.
Put wheel blocks in front and behind each of the front wheels. Lift the rear end of the Tornado with jacks, then rest the vehicle on jack stands positioned so that you can reach the gas tank.
Remove the filler tube attached to the fuel tank with a socket wrench.
Replace the Fuel Pump
Detach the fuel tank from the body of the vehicle by removing the metal gas straps that hold it to the car with a socket wrench. Disconnect the fuel lines running to the fuel tank and gently slide the tank out from underneath the car.
Loosen and remove the fuel pump locking ring holding the fuel pump to the fuel tank with a hammer and brass punch. Be careful to not hit the brass punch too hard with the hammer or else you could damage the locking ring and make it difficult to properly l
Remove the old fuel pump and fuel pump strainer from the gas tank.
Clean the area where the fuel pump locking ring normally sits with a towel. Insert the new fuel pump and strainer into the gas tank and re-tighten the locking ring into place to hold the new pump to the gas tank.
Reconnect the Gas Tank
Reconnect the gas tank by tightening the metal straps around it. Reattach the fuel lines running to the tank and reconnect the gas tank filler tube to the tank.
Raise the vehicle with the jacks, remove the jack stands, and lower the vehicle to the ground. Refill the fuel tank. Remove the wheel blocks. Reconnect the battery cables to the vehicle's battery.
Turn on the engine and check under the car for leaks in the fuel lines or gas tank.
Tips & Warnings
Take extreme care when working around fuel lines and the gas tank. Work in a well ventilated area and make sure there are no flames, sparks or heated objects near the vehicle.
