FASS Filter Thread Adapter (for early Titanium / 95 series pumps with FF-2003)

This adapter allows you to replace old filter part numbers FF-2003 or FF-5712 with new style filters.


In the Summer of 2010 the FASS filter manufacturer relocated outside of the US and discontinued the production of the FF-2003 Fuel Filter. FASS made the change to an American made manufacturer which forced them to change the size of the fuel filter thread. However, the new thread size offers you a much larger selection of available cross references. If you currently have an FF-2003 or FF-5712, those are the ONLY interchangeable filters you can use with your current nipple unless you have this thread adapter.

If you have the FWS-3003 or Donaldson P553203 then you already have the new updated nipple and you do not need this thread adapter.
