Replacing The Fuel Pump In Your '03 Honda Civic Lx

Replacing the fuel pump on a Honda Civic is a relatively simple task that can be accomplished with some basic tools and knowledge. The fuel pump is responsible for delivering fuel from the gas tank to the engine, and while it is generally reliable, it may need to be replaced as the car ages. This guide will outline the steps to replace the fuel pump on a 2003 Honda Civic LX, ensuring your car continues to run smoothly.

Remove backseats

To remove the backseats of a Honda Civic, you will need to firmly grab both ends of the seat and pull upwards, wiggling it as you do so. Take the seats out of the car to avoid damage.

For a 2006 LX sedan without split rear seats, there is a bolt on the left-center of the back of the seat cushion, which you can remove with a 1/4 socket set.

For a 2012 Honda Civic LX sedan, there are several YouTube videos and guides that can show you how to remove the back seat.

For a 2016+ Honda Civic, there is a bolt in the "crack" to the right of the driver's seat seatbeat fastener. There are also two tabs that need to be squeezed and pulled forward, which are centered under the passenger and driver's side of the seat.

Remove pump cover

To remove the pump cover on a Honda Civic 03 LX, you must first remove the back seats. Firmly grab both ends of the seat and pull upwards, wiggling it as you do so. Take the seats out of the car to avoid damaging them.

Once the seats are removed, locate the metal cover. Use a Phillips screwdriver to remove the four bolts that hold the cover in place. Then, tilt the cover out of the way to gain more access to the fuel pump.

Disconnect wiring and hoses

Disconnecting the wiring and hoses is a crucial step when replacing the fuel pump on a Honda Civic 03 LX. Here is a detailed guide on how to do this safely and effectively:

Release Fuel Pressure: Before beginning any work, it is essential to release the fuel pressure at the fuel filter. This is a critical safety step to prevent any accidental discharge of fuel during the subsequent steps.

Remove Rear Lower Seats: Accessing the fuel pump on a Honda Civic 03 LX is typically done through the rear seats. Remove the rear lower seats by firmly grabbing both ends of the seat, pulling upwards, and wiggling it while pulling. Take the seats out of the car and place them somewhere safe to avoid damage.

Locate and Remove Fuel Pump Cover: Once the rear seats are removed, locate the metal cover that provides access to the fuel pump. Use a Phillips screwdriver to remove the bolts holding the cover in place, and then tilt it out of the way to gain better access to the fuel pump assembly.

Final Steps: After disconnecting the wiring and hoses, there are a few more steps to complete before removing the fuel pump. Use a 10 mm socket wrench to unbolt the bracket holding the pump in place. Be cautious not to damage or bend any components during this process. Once the bracket is removed, you can carefully pull out the fuel pump assembly.

Always exercise caution when working with fuel systems, and ensure there are no sources of smoke or open flames nearby to prevent the risk of fire or explosion.

Remove holding screws

To remove the holding screws, you will need to locate them first. They should be visible after you have removed the rear lower seats and the fuel pump service hole cover. Once you have located the holding screws, use the appropriate tool to unscrew them. Be careful not to strip the screws by using the wrong-sized tool or applying too much force. It is also important to keep track of the removed screws so that you can reassemble the fuel pump securely. Place them in a small container or on a magnetic screw mat to avoid losing them.

After removing the holding screws, you will be able to access the fuel pump assembly. Be cautious when handling the assembly, as you do not want to damage or bend the float. Gently pull out the assembly and set it aside, ensuring that you do not spill any fuel. It is recommended to have a drip pan nearby to catch any fuel that may drip from the assembly.

Before beginning this step, ensure that you have released the fuel pressure at the fuel filter. This is an important safety precaution to prevent any accidental fuel leaks or spills during the removal process. Additionally, make sure to unplug the wire connector and disconnect the fuel and return hose before attempting to remove the holding screws.

If you encounter any difficulties or are unsure about any steps, it is always best to consult a professional mechanic or seek advice from a trusted auto repair forum. Working with fuel can be dangerous, so taking the necessary precautions and following the correct procedures is crucial.

Pull out old pump

To pull out the old fuel pump, you must first remove the rear lower seats of your Honda Civic. This is because the fuel pump is accessible through the rear seats.

Firmly grab both ends of the seat and pull upwards, wiggling it as you do so. Take the seats out of the car to avoid any accidental damage.

Once the seats are removed, locate the metal cover and use a Phillips screwdriver to remove the four bolts that hold it in place. Then, tilt the cover out of the way to gain more access.

Now, before you can retrieve the pump, there are a number of items you have to remove. Slip off the boot that covers the wiring connector and then unplug the connector. Next, use pliers to remove the clamp on the rubber hose and disconnect the main fuel line. You will need to squeeze it to remove it.

Finally, you can pull out the old pump. Make sure your drip pan is nearby, as the fuel strainer can drip fuel.
