UWS transfer tanks offer the perfect solution for transporting chemicals, solutions and other non-flammable liquids to your next jobsite. Each tank features corrosion-resistant aluminum construction, a commercial-grade ventilation cap and an optimal fit and capacity to suit your truck and lifestyle. The heavy-duty .125" thick aluminum alloy construction provides the tank with structural strength, while keeping it lightweight and resilient to corrosion. The commercial-grade vented cap allows for proper ventilation of the liquid contents, and the tank is also equipped with commercial-grade mounting flanges for maximum strength in the truck bed. UWS transfer tanks are available in multiple sizes to accommodate any job. Like all UWS truck tool boxes, this product is proudly assembled right here in the USA for style and long-lasting dependability. NOTE: This tank is DOT-compliant for transporting Class 3 combustible fuels only, such as diesel.

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.

UWS | Tough. Reliable.
The kit includes one transfer tank, one filler neck and cap, one 3/8" drain plug, and one key (supplied only with combo models). Hardware for installation is not included and must be purchased separately.
The tank is DOT-compliant for transporting Class 3 combustible fuels only, such as diesel. It is not approved for transportation of flammable fuels such as gasoline and should never be connected to a vehicle's fuel system or used as an auxiliary fuel tank. Do not use for storing or transporting explosives, hazardous materials, propane tanks, acetylene tanks, cutting torches, or other hazardous waste.
Yes. Hardware is not included with the tank. You must purchase your own hardware to install the transfer tank. Installation requires hex bolts, flat washers, lock washers, and nuts for each mounting hole.
You will need: a drill, a 3/8" drill bit, a ratchet, a socket set, a tape measure, and a marker. Proper tools will improve the quality of installation and reduce the time required.
Before drilling into your truck bed, 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.
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.
Drill 3/8" holes in the marked locations on the truck bed floor. Use a 3/8" drill bit. Do not drill into the tank itself; drilling into the tank can result in serious injury or death.
No. Do not cut, weld, or drill into the tank. Doing so could result in serious injury or death.
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.
For each mounting hole, you need one hex bolt, two flat washers, one lock washer, and one nut. Do not over tighten the hardware.
Before securing to the truck bed, ensure the tank is level. Secure the mounting brackets to the truck bed with the specified hardware. Attach the filler neck and cap. Make sure the transfer tank and pump are grounded to avoid static charge, which can result in explosion.
Torque specifications are: M6 bolt 3 ft-lbs, M8 bolt 7 ft-lbs, M10 bolt 16 ft-lbs, M12 bolt 28 ft-lbs (metric); 1/4" bolt 3 ft-lbs, 5/16" bolt 7 ft-lbs, 3/8" bolt 16 ft-lbs, 7/16" bolt 20 ft-lbs, 1/2" bolt 28 ft-lbs (SAE). 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. Static build-up can result in explosion.
You must use an automatic shut-off nozzle. This nozzle is not provided with the tank and must be purchased separately.
Yes. The tank must be vented at all times. Remove the vent cap with caution.
No. Do not pressurize the tank.
Yes. You must use a fuel filter with the transfer tank.
The tank must be lifted only when empty.
No. The tank is for private use only and is not intended to be used commercially.

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. With the transfer tank installed, periodic inspections should be performed to ensure all mounting hardware remains tight. Periodically re-tighten and inspect all components for signs of wear, corrosion and fatigue.
For polished, gloss and other smooth finishes, polish may be used to clear small scratches and scuffs. 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.
Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion.
Yes. You must drill 3/8" holes in the truck bed floor to mount the tank. Before drilling, check under your vehicle to ensure you do not puncture brake lines, fuel lines, electrical wires, or fuel tanks.
No. Hardware is not included. You must purchase hex bolts, flat washers, lock washers, and nuts separately.
You must purchase: installation hardware (bolts, washers, nuts), an automatic shut-off nozzle, and a fuel filter. Spacers may be required if holes fall between truck bed ribs.
The installation is rated as Easy. However, you must drill holes in the truck bed and ensure proper grounding to avoid static charge hazards.
No. The tank is DOT-compliant for Class 3 combustible fuels (diesel) only. It is not approved for gasoline, flammables, explosives, or hazardous materials, and should never be connected to a vehicle's fuel system.
Ensure all bolts, screws, and locks are firmly secured before every trip. Periodically re-tighten and inspect all components for signs of wear, corrosion and fatigue.
