Diesel fuel and cooling water failure are the two most common
problems with marine diesel engines. Now both can be monitored
Supplied with alarm panel, wet exhaust temperature band sensor, fuel filter vacuum sensor and all mounting hardware.

See Raw Water Alarm Page for More Details.

Alarm panel with 95 dB sonic alarm and two red visual lights for fuel filter high vacuum or wet exhaust high temperature alarm. 2.5”x 2.5” x 2””D, flush mount. Requires 2” Dia. cutout

Easy to install nylon coated stainless steel band sensor with fast acting thermistor sensor.  Fits exhaust hoses from 2" to 7".  Supplied with 10 ft of marine grade, tinned cable.  See optional extension kit for exhaust hose larger than 7".  Call for larger cables lengths.

FUEL FILTER VACUUM SWITCH WITH 10 FT(4m) OF MARINE GRADE CABLE. Alarm setpoint 7 to 7- ½ InHg. Alarms before your engine stalls from starved fuel supply. Note: most filter housing are equipped with ¼" NPT port for installation of vacuum gauge.

2-1/2” vacuum gauge. Glycerine filled with stainless steel body, 0-30inHG range. ¼” NPT back center connection. Vacuum gauges are the best diagnostic tool for trouble shooting diesel fuel systems. Change fuel filters not by guessing, but when necessary. Typically filters should be changed when reading is twice initial reading at engine full load. Note: most filter housing are equipped with ¼” NPT port for gauge installation.
