A broken fuel pump is a major headache. After all, it means time and a major fuel pump replacement cost. Sometimes, it takes awhile to get parts, too. However, there is a solution, which is to fix a fuel pump yourself. DIY repairs cut down significantly on fuel pump replacement cost. And the good news is that you don’t have to be a mechanic to fix your fuel pump. With some attention to detail and following the right steps, just about anyone with basic mechanical knowledge can make the repairs.
Before you start a fuel pump replacement, you’ll need to have the right tools for the job. Before you start, be sure that the fuel pump replacement parts that you have are the right fit for your car. This is especially important if your car is your primary mode of transportation. Once you take the gas tank and fuel pump out, your car won’t be going anywhere.
Check for Damage
Prior to a fuel pump repair or replacement project, look for damage. Since you’ll be removing your car’s fuel tank during the repair process, now is a great time to check the tank for leaks, cracks, corrosion, or other signs of damage. If you notice significant damage, you may need to repair or replace the fuel tank as well. While you’re looking at the tank, check to see if it has a drain plug on the bottom. If so, it will be much easier to get rid of fuel that’s in the tank.
Once you’ve determined that you have the right parts for a fuel tank replacement and the fuel tank isn’t broken, it’s time to get started.
First, you’ll want to eliminate electricity going to the fuel system. You can do this by disconnecting the battery cable. Then, you’ll need to put your car up on jack stands or lift it up. In either case, the car should be placed on a firm and level surface. You can also lift the car up so that you have access to the underbody. It also helps to have a flashlight or other source of light so that you can clearly see what you’re doing. The next step requires alleviating pressure in the fuel system. This process varies by vehicle, so you’ll need to check your owner’s manual or service manual to figure out the process for your make and model. The manual will also provide instructions for disconnecting the fuel tank’s filler neck. This is the next step to complete. After that, you’ll want to use a jack and another firm support structure, such as a block of concrete or wood, to hold up the fuel tank. Next, remove the bolts and disconnect all vent hoses, fuel lines, and wire connections. After all the parts have been disconnected, use the jack to remove the tank from the car. The tank should be cleaned so that debris doesn’t contaminate the fuel tank upon removal. Then, you’ll need to take the fuel pump assembly out of the fuel tank. This probably requires removing a plate and its accompanying screws or bolts first. Once the old pump is out, you can put a new one in. Be sure to reconnect all wiring connections, fuel lines, and vent tubes. The fuel filler tube should be replaced, too. Lastly, reconnect the negative battery cable.
After the new fuel pump is installed, it’s time to take your car for a drive. This ensures that the fuel pump has been installed properly and that everything is working as it should. If you notice any problems, you can try troubleshooting the issue or contact a mechanic for repairs.
