Warranty: Limited Lifetime Warranty (One-Year Finish, One-Year Parts)
Finish: GLOSS BLACK POWDER COAT
Material: Aluminum
Part Type: TRANSFER TANK
The hammerhead-style transfer tank is engineered to be the universal transfer tank for all full-size trucks. It features a unique narrowed base that fits between the wheel wells in the truck bed, even on short-bed pickup trucks (verify fitment using the product dimensions). This innovative L-shaped transfer tank is ideal for safely and effectively transporting diesel and other non-flammable liquids. It is constructed with heavy-duty .125" thick aluminum alloy and has a durable gloss black powder coat finish. The hammerhead-style transfer tank is also equipped with a lockable, vented cap that allows for easy filling and provides extra security when your truck is left unattended. It comes with internal baffles to promote a smooth flow of liquids and to help prevent sloshing. Finally, to easily drain the tank whenever necessary, a drain plug is integrated into the base. NOTE: Will not fit short-bed trucks with a gooseneck hitch installed (75-gallon transfer tank recommended).

UWS designs and builds heavy-duty truck tool boxes and storage for tradespeople and truck owners. The line covers crossover and side-mount boxes, chest boxes, underbody boxes, transfer tanks and dog boxes. Every aluminum box is designed, fabricated and welded in Perry, Florida, with construction aimed at job-site abuse, road vibration and daily use.
UWS is a leading manufacturer and designer of truck tool boxes and truck accessories, and a Lippert brand. The company's focus is narrow and deliberate: storage that stands up to being opened and slammed shut dozens of times a day, loaded past what looks reasonable, and left outdoors in whatever weather the job brings. Its customers are electricians, plumbers, contractors, farmers, outdoorsmen and truck owners who treat a pickup as a working tool rather than transport.
The catalog covers the full range of bed storage. Crossover boxes sit across the bed behind the cab in single-lid, gull-wing, secure-lock and low-profile styles, so there is a fit whether the priority is capacity, rear visibility or working under a tonneau. Side-mount boxes mount along the bed rails and keep the bed floor free for cargo, while underbody boxes tuck beneath the frame rails of service bodies and flatbeds.
Beyond the bed, UWS makes portable chest boxes that move between vehicles and the shop, transfer tanks and combination tank-and-toolbox units for crews working away from fuel supply, and insulated, ventilated dog boxes for hunters and handlers.
Manufacturing sits at the centre of the brand's identity. Every UWS aluminum tool box is designed, fabricated and welded in Perry, Florida, by tradespeople with decades of experience, and the company's Rooted in Trades initiative is built around that connection to skilled manual work. Boxes use heavy-gauge aluminum, continuous welds at the seams, weather stripping to seal against rain and dust, and locking systems intended to resist tampering. The practical result is storage that keeps tools dry, organized and where they were left.

The tank is designed for Class 3 combustible fuels such as diesel only. It is not compatible with diesel exhaust fluid (DEF) or other corrosive materials. Do not use it for flammables, explosives, hazardous materials, hazardous waste, gasoline, solvents, gun powder, dynamite, propane tanks, acetylene tanks, or cutting torches.
You will need a drill, 3/8" drill bit, ratchet, socket set, tape measure, and marker.
Yes. Hardware is not included with the tank. You must purchase your own hex bolts, flat washers, lock washers, and nuts to secure the mounting brackets to the truck bed.
You must install a fuel filter and use an automatic shut-off nozzle (neither is provided). The tank must be vented at all times and must be grounded to avoid static charge buildup.
Yes. You must drill 3/8" holes in the truck bed floor at locations marked by the mounting brackets. Before drilling, you must check under your vehicle to ensure the drill location does not puncture, cut, or obstruct any brake lines, fuel lines, electrical wires, fuel tanks, or other components.
Before drilling, check under your vehicle to ensure the drill location does not puncture, cut, or obstruct any brake or fuel fluid lines, electrical wires, fuel tanks, or other components. Precaution must be taken that all fasteners near the fuel tank do not create the possibility of fuel tank puncture or other damage during a collision. After drilling, treat or seal all fasteners and exposed metal in any holes to prevent corrosion.
You must drill 3/8" holes in the truck bed floor at the locations marked by the mounting brackets.
Push the tank up to the truck cab and center it side-to-side. Make sure the tank is fully supported by the truck bed floor. Use the mounting brackets as a guide to mark the hole locations before drilling.
Each mounting bracket hole requires one hex bolt, two flat washers, one lock washer, and one nut. Do not over tighten the hardware.
If any holes fall between the ribs on the truck bed floor, spacers will be required between the floor and mounting bracket for proper installation.
Before securing the tank to the truck bed, ensure the tank is level. Align the drilled holes with the mounting brackets and secure with the hex bolts, flat washers, lock washers, and nuts.
Torque specifications depend on bolt size: M6 or 1/4" bolt = 3 ft-lbs; M8 or 5/16" bolt = 7 ft-lbs; M10 or 3/8" bolt = 16 ft-lbs; M12 or 7/16" bolt = 20 ft-lbs; 1/2" bolt = 28 ft-lbs. These are general guidelines. If purchasing hardware, use the torque specifications provided with that hardware.
The transfer tank and pump must be grounded to avoid static charge buildup. Static buildup can result in explosion.
No. Do not pressurize the tank.
No. Do not cut, weld, or drill into the tank. Doing so could result in serious injury or death.
The tank must be lifted only when empty.
Yes. This product can reduce the driver's ability to clearly see roadways, vehicular or pedestrian traffic, and other objects through the rear and side windows of the vehicle, which may cause an accident. Extra precaution should be taken when driving a vehicle with this product.
Never exceed the vehicle manufacturer's recommended capacity.
Ensure all knobs, bolts, screws, straps, and locks are firmly secured before every trip. Periodically re-tighten and inspect all components for signs of wear, corrosion, and fatigue. With the transfer tank installed, periodic inspections should be performed to ensure all mounting hardware remains tight.
Mild automotive detergent may be used to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes, or other similar products that may damage the finish. For polished, gloss, and other smooth finishes, polish may be used to clear small scratches and scuffs on the finish.
Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion.
No. It is DOT-compliant for diesel only, not gasoline or flammable fuels.
Drill, 3/8" drill bit, ratchet, socket set, tape measure, and marker. You must also purchase your own hex bolts, flat washers, lock washers, and nuts.
Yes. You must drill 3/8" holes in the truck bed floor. Check under your vehicle first to avoid puncturing brake lines, fuel lines, or electrical wires.
Use 16 ft-lbs for 3/8" bolts, 7 ft-lbs for 5/16" bolts, or 3 ft-lbs for 1/4" bolts. Refer to hardware specifications if different sizes are used.
Yes. The tank and pump must be grounded to avoid static charge buildup, which can cause explosion.
