Bowl Kits With Fuel Heaters
A Racor in-bowl fuel heater is a critical filter component for cold weather operation. An electric relay allows a switch to control the heater operation. The fuel heater turns on when fuel temperature drops below 45°F (7°C), and off when fuel temperature reaches 85°F (29°C). During operation, the in-bowl heater provides convective heat directly to the surface of the filter to melt clogging paraffin wax crystals and allow the fuel to flow.
In-bowl heater and relay kits are available in 12 and 24 volt DC configurations. These kits are used to preheat the filter by turning the ignition switch to the accessory position and waiting a minimum of 5 minutes before starting the engine. After the engine starts in extreme cold weather, full power may not be available until warm re-circulated fuel returns to the fuel tank.
