When using another form of fuel filtration, such as the Platinum or Titanium FASS Fuel Air Separation Systems, the factory fuel filter is no longer needed. This delete kit keeps the water in fuel sensor and the factory heater in place and operational. Performing fuel filter maintenance is made much easier!
This kit must be used with a 10 micron or less fuel filter. We recommend a 3 micron fuel filter for maximum filtration. A port is included for fuel pressure sending units.
