Replacing The Fuel Pump In A 1990 Honda Civic Diy Guide

If your 1990 Honda Civic is experiencing starting issues, a faulty fuel pump could be the culprit. This hydraulic device pumps gas from the gas tank to the engine through fuel lines. While fuel pumps are generally reliable, they will likely need to be replaced as your Civic racks up the miles. Replacing the fuel pump is a relatively simple process, but if you have any doubts, it is best to take your car to an auto shop. This article will provide a step-by-step guide on how to change the fuel pump in your 1990 Honda Civic.

Remove backseats

To remove the backseats of a 1990 Honda Civic, start by firmly grabbing both ends of the seat. Pull upwards, wiggling it as you do so. Take the seats out of the car and set them aside to avoid damage.

There are small latches on the front edge of the seat that you can undo with a flathead screwdriver. There is also a 10mm bolt located in the crack to the right of the driver-side seat beat fastener. There are two tabs centered under each side of the seat that need to be squeezed and pulled forward to fully remove the backseat.

Remove pump cover

To remove the pump cover of your 1990 Honda Civic, you will first need to remove the back seats. This is done by firmly grabbing both ends of the seat and pulling 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 metal cover in place. Then, tilt the cover out of the way to gain more access to the fuel pump.

It is important to note that you should not smoke while working near fuel, as this could lead to a sudden fire or explosion.

Disconnect pump

Disconnecting the fuel pump on a 1990 Honda Civic is a complex task and should be performed with caution. Here is a detailed, step-by-step guide on how to do it:

Remove the back seats: This is necessary to access the fuel pump, which is located underneath the rear seats. Grab both ends of the seat and pull upwards, wiggling it as you do so. Take the seats out of the car and set them aside.

Locate the metal cover and remove it: Once the rear seats are removed, you will see a metal cover. 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.

Slip off the boot covering the wiring connector and unplug the connector: Before removing the fuel pump, you need to disconnect the wiring. Use your hands or a suitable tool to slip off the boot covering the wiring connector, then unplug the connector itself.

Remove the clamp on the rubber hose using pliers: The rubber hose needs to be disconnected from the fuel pump. Use a pair of pliers to carefully remove the clamp securing the hose.

Disconnect the main fuel line: This step requires you to squeeze the main fuel line to disconnect it from the pump. Be cautious, as fuel may still be present in the line.

Unbolt the bracket using a 10 mm socket and ratchet: The fuel pump is secured by a bracket with bolts. Use the appropriate tools to unbolt the bracket and completely detach the fuel pump.

At this point, the fuel pump should be successfully disconnected and ready for removal. Remember to have a drip pan nearby to catch any fuel that may drip from the fuel strainer during the removal process. Always exercise caution when working with fuel to avoid any potential safety hazards.

Remove strainer

To remove the strainer of your 1990 Honda Civic's fuel pump, you will need to first remove the backseats of your car. The fuel pump is accessible through the rear seats. To do this, 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.

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.

With the cover removed, there are several items you will need to remove before the pump can be retrieved. Slip off the boot that covers the wiring connector and unplug the connector. 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.

Now that the pump is disconnected, grab it and pull it upwards. Make sure your drip pan is nearby, as the fuel strainer can drip fuel. Once the fuel pump strainer is out, disconnect the top plug and remove the strainer clamp.

Install new pump

Now that you've removed the old fuel pump, you're ready to install the new one.

First, slide the new pump into place. Reconnect the plug and fuel strainer, and slide it back into the fuel tank opening. Bolt the bracket back in place with six screws to secure the pump.

Next, reconnect the fuel line and rubber hose. Plug the connector back in, and reattach the connector boot. Finally, reattach the access cover with the five bolts, and reinstall the back seat.

You've now successfully installed a new fuel pump in your 1990 Honda Civic!
