ADDING A PERFORMANCE LIFT PUMP
The FASS lift pump is designed to not only increase the amount of fuel going to the injection pump, but also to ensure that the fuel is free from water, dirt, and air. It's comprised of three main parts: a pump/filtration unit with a 95-gallon per minute fuel pump, water separator, and fuel filter. The system has its own pick-up that gets mounted in the tank, and although the stock pump and filter in Dodge applications don't need to be removed from the truck, they will no longer be used.
While performing the typical duties of pumping and filtering fuel, the FASS also removes air from the fuel. Like most liquids, diesel picks up air when it is agitated and vibrated during normal driving conditions. The air in the fuel can cause fluctuations in fuel pressure, rob the engine of performance and fuel economy, and also increase emissions. Using a patented port manifold and fuel filter, the FASS system separates the air from the fuel and returns the air/fuel back to the tank through the filler neck while another line supplies the injection pump with clean air-free fuel.
In order to learn more about the FASS system and to see how it installs, we met up with Kelley Evans from PDI at Industrial Injection in Salt Lake City, Utah. Dallas Hunt assisted Evans with the installation of a FASS 95/95/1008 system on a 6.7L Dodge Cummins.
