What is a FASS System

What is a FASS Fuel Systems?  A FASS Fuel System is a direct replacement fuel pump for diesel engines; which features a dual filtration system that is far superior to your factory fuel system in every way.  FASS stands for (Fuel Air Separation System) and is designed to remove Air, Water and Debris from your diesel fuel; while providing consistent fuel pressure to your engine through a larger and more powerful motor.  Common uses of a FASS system includes performance improvements for towing, racing and daily driving (Fuel Mileage Gains).  Kits are designed for common engines such as the Dodge Cummins, Ford Powerstroke and GM Duramax.  However, we also offer universal pumps that can be custom designed to fit any diesel engine including applications for class 8 semi's, tractors, boats and heavy duty equipment.

The FASS fuel pump called the Titanium Series is designed with a large motor powerful enough to supply fuel to any diesel engine including a Semi engine used in Class 8 trucks. The fuel is passed through a dual filtration process that will remove air, water and debris; providing the cleanest fuel of any diesel fuel filter on the market.  To make the Titanium Series the best pump on the market FASS Fuel Systems utilizes important exclusive features you can only find in a FASS Fuel System. 

  • FASS Silencing Technology (FST) was developed by the engineering team here at FASS Fuel Systems to help reduce the noise created by aftermarket fuel and air separation diesel lift pumps. By using radius cuts, tighter tolerances on all gears and a high quality military Spec’d Coating over the aluminum base, FASS Fuel Systems was able to develop the quietest fuel air separation system on the market.
  • Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the diesel lift pump by creating smooth flowing cuts within the aluminum housing.  This prevents the reintroduction of air and vapor back into the fuel and also to prevent stagnate fuel pockets from forming within the corner of a 90 degree bend. FASS Fuel Systems Titanium Series Diesel Fuel Pumps are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts, lesser competitors commonly use T-Bone and square 90 degree fittings that can limit fuel flow, cause restrictions and reintroduce air back into your fuel.
  • Mass Flow Return (MFR) technology is used to continually “polish” your fuel by keeping a positive pressure on the fuel being delivered to the engine and returning the fuel, that’s not yet needed, back to the tank after it has been passed through the filtration process, removing dirt, air, vapor and water. This means your fuel is being constantly moved and cleaned, guarantying that your diesel truck always has the freshest and cleanest fuel possible.
  • Bolt On Bracket Mounts are the latest update we have made to our Titanium Series lift pumps.  Old mounting styles required drilling or welding when mounting your new pump.  This has now been simplified with our new bolt on brackets that utilize your Ford Super Duty factory bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Series lift pump takes only minutes and all brackets are made from machined steel for superior support and strength.

In addition to all these great benefits the Titanium Series diesel fuel pumps comes with the largest diesel fuel filters of any aftermarket pump which only need to be replace every 30,000 miles or at least once a year.  Other features include option heating ports for both coolant and electric heats that are perfect for cold winter weather and multiple flow rates for optimal horsepower potential.
