A fuel pump needs replacement if it becomes faulty and cannot perform as expected. Different vehicle models have varying ways to replace the fuel pump. However, most car models use a standard method of replacing a high flow fuel pump. If one has an e85 fuel pump that they want to replace, the steps to achieve perfect results are incredibly straightforward.

Steps for fuel pump replacement

Replacing a high flow fuel pump involves following steps that happen in three phases. Each phase of fuel pump replacement complements the other. Therefore, one must ensure one phase is complete before moving to the next for the process to be successful.

Taking necessary safety measures

The first phase involves ensuring that all the safety measures are in place to protect the person replacing the pump, the fuel pump itself, and the other parts of the car that will be involved in the process. Gather all the safety gear like gloves, overall, and glasses and put them on before the function begins. One should ensure that they have cleaning products ready to clean spills right at the moment they happen to prevent staining. When replacing a fuel pump, one must be in a well-ventilated space. Never smoke or allow any open flame in the area you are operating. In case of a fire, one needs to have a fire extinguisher ready.

Removing the old fuel pump

If one is replacing a pump, there is already an old or faulty fuel pump in the vehicle. Gather all necessary tools that will aid in removing the fuel pump. The first step in this phase is parking the car on a surface with no bumps, turning it off, and then attaching the rare tires with wheel chocks. After that, the individual need to open the car’s hood and remove the battery connection. Using a jack, lift the vehicle to the desired height and set the jack stands. Unfasten the fuel door to reach the filler neck.

Get under the car, take off the straps around the fuel tank and bring down the gas tank a bit. Reach the vent hose that attaches to the filler neck and unclamp it. That will allow you to remove the fuel compartment altogether. In this way, one can access the fuel pump easily. If you can see the fuel pump, remove any mounts that connect to the pump and safely remove it.

Installing the high flow fuel pump

The last phase is placing a new fuel pump on the vehicle. With the old fuel pump out, installing a new one involves reversing the process. Place the new pump in position and mount all the connections you removed in the last step of the previous phase. Ensure the bolts are tight enough to maintain the fuel pump. With the pump back to its position, put the fuel tank and attach the vent hose to the filler check. Once you make the necessary attachment, raise the fuel tank back to its position and mount new clamps. One can reconnect the battery and ignite the vehicle to see if it starts. If all is well, lower the car and remove the wheel chocks.

Conclusion

After completing the process of replacing a high flow fuel pump, it is essential to take a test drive to ensure that the new fuel pump operates appropriately. When a car has issues, the user should not conclude about replacing the pump. Conduct necessary diagnosis to determine if the fuel pump is defective. Also, it is always good to seek professional help if the process seems complex to you.
