How to Replace Fuel Pump Assembly in a 1991 Honda Accord LX
The fuel pump in your vehicle is the pump that forces fuel from the fuel tank to your motor. In the 1991 Honda Accord LX, the fuel pump is electronic instead of mechanical, meaning that an electric motor pumps the fuel. Since the 1991 Accord LX is fuel injected, the fuel needs to travel with a high rate of pressure to the motor. The fuel pump assembly is located inside of the fuel tank on the 1991 Accord LX so the fuel tank needs to be removed prior to replacing the pump assembly.
Instructions
- 1
Disconnect the battery from the motor by removing the wires from the poles on the battery.
2Drain the fuel tank by removing the drain bolt from the tank. Remove the fuel tank from the vehicle and use a jack to support it so it doesnt fall to the ground. Make sure all hoses and connectors are unplugged from the fuel tank.
3Unscrew the six mounting nuts that are located on the fuel pump bracket and disconnect the fuel lines that are connected to the fuel pump bracket. Lift the old fuel pump assembly out of the fuel tank to remove it. Be careful of dripping fuel from the old fuel pump assembly.
4Insert the new fuel pump assembly into the fuel pump access hole that the old pump assembly came out of. Make sure that the holes on the new pump go over the bolts comfortably and the pump isnt forced inside.
5Replace the mounting nuts over the bolts to secure the new fuel pump assembly in place. The nuts should be torqued to 4 ft. lbs. of torque. Reconnect the fuel lines and tighten the clamps to secure them from leaking.
6Reinstall the fuel tank underneath the vehicle and reconnect the hoses and connectors that were originally connected to it. Replace the fuel that was drained from the tank and reconnect the battery to the motor. Start the motor to test the newly replaced fuel pump assembly.
