This coolant-heated fuel pick-up accelerates switch-over times in the winter by essentially “heating on demand.” This steel tube heats the oil at the source of the fuel pick-up, allowing for the most efficient heating of the oil.

The Hot Fox is constructed of stainless steel, so there is no chance of contamination between fuel and coolant. It can be rotated in the tank for easy hose alignment. It fits in a 1-5/8” hole and has a low-profile, less than 1-1/4”above tank. Three ½” FPT Ports allow for multiple set-ups. Due to the variety of configurations possible, these barb fittings are not supplied with the unit. Multiple depth sizes are available to fit tanks between 10” and 29” deep. Five-year (5-year) or 600,000 mile Warranty included!

Get faster warming and cleaner installation with the HOT FOX fuel warmer from Arctic Fox.

It truly is an in-line warmer that installs in the fuel tank. The simple 1 ½ " (38mm) diameter stainless steel tube inserts in the tank through a 1-5/8” Hole cut in the top of the tank or a standard USA fuel gauge sending unit opening. Coolant passages inside the tube surround the fuel standpipe to provide excellent heat rise. The internal fuel line features an exclusive spiral design to offer larger heat exchange surface from warm coolant to cold fuel.

Recommendation: The HFG & SHH Series HOT FOX fuel warmer can mount into a standard USA fuel sending gauge opening. For installations into non-reinforced gauge hole openings in tanks manufactured of 14 gauge (.075"/1.9mm) and lighter steel or .100"/2.5mm and lighter aluminum, the appropriate adapter kit KT-826F, KT-827C or KT-831 CS is suggested. For extreme vibration applications and all applications involving horizontal mounting, the A-1721 or A-2060 is suggested.

Low Profile Installation

The low profile design fits where other fuel warmers can’t. For most efficient heat transfer, choose the longest HOT FOX fuel warmer available for your tank diameter/depth. Each unit comes with a 2" (51mm) extension fitting: A-858.
