Capacity is 24 gallons. The rear face is angled to allow access to the spare tire. 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 the bottom, front and back, and a 2nd that's 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. The Trunk Tank has a large filler neck, provide with an aluminum fill cap that unscrews, with a knurled outer surface for easy gripping. The Sedan tank is fitted with 4 gusseted angles TIG-welded to the tank, each with a 9/16" hole to accept a machine bolt. The gusseted angles are positioned to rest against the wheel wells, which are then marked and drilled, and 1/2" machine bolts are inserted in the holes, with stainless steel Nyloc bolts installed from the tire side of the wheel wells securing them.
