Fits: Fits 500 (manufacturered after 2002), 900 and 1000 model Turbine Series fuel filter/water separators, including UL marine listed models (MA versions).
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.
NEW UPGRADED FEATURES:
Stainless Steel case and face increased from 2.0 inches to 2.5 inches diameter for easier reading
The improved cases feature a pressure relief valve to adjust to ambient barometric pressure changes
Acrylic lenses upgraded to polycarbonate
Needle stops replaced with internal locking mechanism to prevent damage due to an accidental overpressure
Internal sealing at the fitting, lens, and pressure relief valve reduces the likelihood of internal contamination by splashing fluids
Features:
Gauge Thread Size (threads that screw in to top of t-handle): 1/4-18 NPTF
T-handle Thread Size (threads that screw in to top of turbine filters): 9/16-18 UNF - 2A
T-handle Thread Length: 1"
Gauge reads vacuum -30 to 0 "Hg
No tools required
UL approved for use on marine listed models (MA versions)
Lowers operational costs and extends filter life
*500FG Turbine Series made before January 2002 do not have enough thread depth in the center tube pipe to accept the RK19671 T-handle gauge. If current T-handle threaded shaft portion is less than 1" long then the filter housing was made before 2002.
