Customers can use the website’s year-make-model dropdown to find parts specific to their vehicle. Many vehicles do use the same fuel pump but we have developed installation kits that are specific for certain makes and models as well as more universal kits that will fit a wider range of vehicles that use the same pump.

There are several things you can do to keep your fuel pump running smoothly. These include keeping your fuel tank at least a quarter full to prevent the fuel pump from overheating, using high-quality fuel, and regularly replacing the fuel filter.

Another great way to keep your fuel pump healthy is by replacing the strainers and pre-filters regularly.
