The Hot Fox fuel heater from Arctic Fox is an in-line fuel heater that installs in the fuel tank.

A 1 ½-inch diameter stainless steel tube inserts into the tank through a standard USA fuel gauge sending unit opening. Coolant passages inside the tube surround the fuel standpipe to provide heat rise.

The internal fuel line features a spiral design to maximize heat exchange between warm coolant and cold fuel.

The Hot Fox comes in a variety of lengths for different fuel tank sizes and each unit comes with a 2-inch extension fitting.
