FASS Fuel Systems, Pumps, Filters

Shop below for FASS fuel air separation systems with filters, stand alone fuel pumps, replacement filters, or just miscellaneous accessories. When selecting a FASS fuel system for your Dodge Cummins, Ford Powerstroke, or GM Duramax the options can be overwhelming for sure! Do I need a FASS system with filters or just a pump? I want a FASS system with filters, should I go with the Titanium Series, or Platinum series? I just want a fuel pump without filters, should I get the standard or adjustable fuel pump? What flow rate do I need? I have a stock Cummins with a VP44 injection pump, is the DDRP pump best? At Thoroughbred Diesel we are a real shop that works on diesels and installs all the products we sale. If you have questions stop clicking and call us toll free at 866-737-4966, we offer free advice daily and are a experienced diesel company.
