How to Replace an Acura Rl Fuel Pump

by Dan Ferrell

The electric fuel pump on your Acura RL model provides the pressure and flow for the metering section of the fuel system. However, the spinning mechanism inside the pump, which produces a smooth pressure along the fuel lines, may fail due to component wear or malfunction. Without adequate system pressure, the engine will fail to start. However, you can access the fuel pump on your RL model through the back seat without lowering the fuel tank. And following these steps, you can replace the bad unit with a new one.

Relieve the Fuel System Pressure

Detach the black or negative cable from the battery using a wrench.

Loosen the fuel filler cap.

Locate the fuel filter on the upper, driver side of the firewall inside the engine compartment.

Cover the top of the filter with a shop rag and loosen the top fuel line bolt on the filter using a tube wrench.

Tighten the filter bolt again as soon as the fuel system pressure is relieved.

Remove the Fuel Pump

Pull the retaining strap from the back of the rear seat and lift the seat off the floor.

Unfasten the three screws from the floor access-panel door using a Phillips screwdriver, and remove the door.

Unplug the fuel pump electrical connector.

Detach the fuel lines from the fittings on top of the fuel pump assembly. Press the lock tabs and pull the lines from the plastic connectors and away from the fittings.

Unscrew the mounting nuts from the pump assembly flange using a ratchet, ratchet extension and socket.

Lift the fuel pump assembly off the fuel tank and discard the O-ring underneath the flange.

Install the New Fuel Pump

Install the new pump on the pump assembly.

Set the fuel pump on the fuel tank along with a new O-ring.

Tighten the mounting nuts on the pump assembly flange using the ratchet, ratchet extension and socket.

Connect the fuel lines to the fittings on top of the fuel pump assembly.

Plug the fuel pump electrical connector.

Set the floor access-panel door and tighten the three screws using the Phillips screwdriver.

Replace the rear seat.

Tighten the fuel filler cap.

Attach the black or negative cable to the battery using the wrench.
