Last Ones! Fleetguard 3843722S Fuel Heater Thermostat Switch With Plug Wire

Fuel heater thermostat switch for Dodge Cummins 1994-1998 12 Valve. This is the thermostat switch in the pre-filter/heater that is located just in front of the lift pump. When this thermostat fails and sticks on, the heating element overheats and warps causing a leak in the fuel system.
