The larger sizes (97 US gallon with non-recessed HotFox, 85 gallon with recessed and concealed HotFox) will fit most domestic long-bed pickups - Ford 6.9 and 7.3 pre-Powerstroke, Ford Powerstrokes, Dodge Cummins 12-valve and 24-valve, Chevy/GMC 6.2, 6.5 and Duramax. Double-check your truck before ordering! Dimensions are 59" left-right, 20 front-back and 19" high.

The smaller sizes (48 US gallon with non-recessed HotFox, 43 US gallon with recessed and concealed Hotfox) will fit all of the above long bed trucks plus the short-bed versions of the above trucks, but be sure to double-check your truck before ordering! Dimensions are 58-1/2" left-right x 11-1/2" front-rear x 19" high.

The recessed-and-concealed HotFox models (see the Photo Gallery, then Aluminum Tanks) conceal and protect the HotFox, it's hoses, and the fuel level sender under a removable cover that slides rearward and off should you need to access either the 'Fox or the sender.)

The truck tanks are constructed of 3/16" 5052-H32 aluminum, TIG welded. They are internally baffled, for anti-sloshing/prevention of fuel starvation when cornering or in off-camber situations, and the baffles are also 3/16" 5052 aluminum. The baffles also serve as structural ribs - preventing the long sides of the tanks from "oil-caning" as well as taking stress off the perimeter welds.

Additionally, the tanks are not constructed of the usual 6 sheets, but rather of only two C-shaped sections - one piece that's bent to become the bottom, front and back, and a 2nd that's bent to form the top and two ends. This construction results in a stronger tank.

All tanks are supplied with a tube-type fuel level sender - we've found that float-arm type fuel level senders fail in time in a WVO application. All tanks are supplied with 1 -brass 3/8" NPT (National Pipe Thread) X 3/8" hosebarb fitting for fuel return. The HotFox coolant-fuel heat exchanger/heated fuel pickup is your fuel supply/fuel out from the tank. (Each HotFox is supplied with 3- 1/2" NPT female ports - one is coolant in, another is coolant out, and the third is fuel out.)

All tanks are provided with a brass 3/8" NPT x 3/8" hose barb fitting, for a tank vent. Generally, best practice is to run a hose from our tank that T's into the stock diesel tank's vent line near where that vent line T's into the stock rubber fuel filler hose. If this is difficult or impossible, we sell one-way check valves that can be plumbed into your WVO tank's vent line to prevent fuel spillage from the vent hose.

Each tank is shipped with a large removable aluminum inspection plate/hatch in the top, in the even the tank needs cleaning. All tanks are provided with a polished stainless steel marine-type fuel filler with a removable fuel filler cap that requires a special (provided) key that discourages tampering with your fuel.

The truck tanks are shipped with galvanized mounting straps with round stainless T-nuts that are captured by the ends of the straps - you?ll need to supply 1/2? x 13 machine bolts of the correct length for your application. The straps are not attached to the tank, so that you can position them to clear anything under the bed of the truck that would be in the way.
