The Signal Filters SMART Filter System is an integrated system for the Recreational / Marine industry, combining a marine fuel filter, marine fuel water separator and real time water in fuel sensor. It provides the advantage of water in fuel sensor while maintaining the simplicity and reliability of a spin on fuel filter.
Signal Filters filters the fuel, removes water and senses water in the fuel separator (diesel or gasoline) before the water can enter the engine. Water in the engine fuel system can cause engine damage, hard starting, loss of power, misfiring, or stalling. The Signal Filters SMART fuel filter system is designed to let you know when it needs to be serviced.


ADVANTAGES:

  •  Real time water level sensing in the bottom of a fuel filter water separator
  •  Easily serviced metal spin on fuel filter
  •  Patented technology allows water level sensing for gasoline and diesel fuel engines
  •  Corrosion resistant construction – 316 stainless steel filter head
  •  Designed to UL 1105, ABYC and Coast Guard fuel system requirements
  •  No plastic bowl
  •  Wireless capability
  •  See product page for specs and more info.
