These systems are available both as a stand alone pump, as well as with an integrated fuel filter and water/air separator, which will help to prolong pump and injector life by removing any particulate matter and air to prevent cavitation, which the factory system cannot do.īesides lift pumps, we also carry an assortment of other fuel related items for your Cummins. This is why we recommend one of our high pressure fuel pumps from such companies as FASS or Pureflow. Doing so has helped tremendously with lift pump failure, however, with any type of engine enhancement, they are still EXTREMELY prone to failure (we've still seen numerous pumps fail on stock powered trucks). In model year 2005, Dodge began to mount the fuel pump inside of the fuel tank. The two main issues with this setup were that it absorbed a lot of heat from the block, and that it required the pump to "pull" fuel, as opposed to "push" fuel as it was originally designed to do.
