When the original pump was installed on your vehicle, it was installed with a clean fuel tank. This is because any debris that sits in your tank can damage the new pump you’ve invested in. If you are going to replace your fuel pump, it is important that you clean your fuel tank too. With the right tools, the process only takes about an hour. If you would like to learn the steps of this process see the video below for an easy how-to. You can find the Delphi Fuel Tank Cleaning Kit here.
