Vacuum/restriction indicators monitor filter condition as the filter slowly becomes clogged with contaminants. As the filter gets dirty, restriction increases and less fuel is delivered to the engine causing the engine to lose power and eventually stall. By installing a vacuum/restriction indicator in your fuel system, visual monitoring of filter condition is possible at a glance, increasing fuel system troubleshooting efficiency, eliminating guess work, and lengthening filter change out intervals.
Fits: 500 (manufacturered after 2002), 900 and 1000 model Turbine Series fuel filter/water separators, including UL marine listed models (MA versions).
