Step 1: Disconnect the Car Battery
The first step in how to replace a car’s fuel pump is to disconnect the car battery. This ensures that there is no power running through the system while you’re working, preventing accidental sparks or electrical shorts.
Step 2: Relieve the Fuel System Pressure
Next, relieve the pressure in the fuel system. You can do this by either using a fuel pressure relief valve or by removing the fuel pump fuse and cranking the engine for a few seconds. This step is crucial to avoid fuel spillage when disconnecting the fuel lines.
Step 3: Lift the Car
Using a jack and jack stands, lift the car to access the fuel tank. Make sure the car is securely supported before proceeding. This step is important for safely accessing the fuel pump.

With the fuel lines disconnected, you can now remove the old fuel pump. Use your socket set to remove any bolts securing the pump. Once free, lift it out of the tank.
Step 7: Install the New Fuel Pump
Place the new fuel pump into the tank and secure it with the bolts. Be sure the new pump is positioned correctly and that the fuel lines are reconnected securely.
Step 8: Reassemble and Test
Reassemble the fuel tank, reconnect the fuel lines, and reattach the fuel tank to the car. Once everything is in place, reconnect the car battery. Start the engine and check for leaks or unusual sounds. Your new fuel pump should now be functioning properly.
