A UWS steel transfer tank is the perfect way to outfit your truck for working on the farm, the construction site or other tough jobs. It allows you to safely and effectively transport non-flammable liquids -- such as chemicals, pesticides, diesel fuel or even water -- to other vehicles and equipment. This 45-gallon steel rectangle transfer tank is constructed from 14-gauge steel, welded into a single piece to eliminate leaks. It features a lockable, commercial-grade, vented cap for easy filling and a drain plug for convenient emptying. It is also equipped with lifting hooks on the back for easier moving in and out of the bed of your truck, as well as welded mounting tabs for secure installation (mounting hardware not included; remove all liquid contents prior to tank relocation). All UWS steel transfer tanks are built for safety, featuring internal baffles to resist sloshing and promote an even flow of liquids. They are also 100% pressure-tested for safety. This particular 45-gallon steel transfer tank comes with a matte black powder coat finish for excellent corrosion resistance. 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.

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 such as hex bolts, flat washers, lock washers and nuts must be purchased separately.
The tank is DOT-compliant for transporting Class 3 combustible fuels only, such as diesel. It is not approved for 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 it for storing or transporting explosives, hazardous materials, propane tanks, acetylene tanks, cutting torches or other hazardous waste.
No. The tank is not compatible with diesel exhaust fluid (DEF) or other corrosive materials.
You will need a drill, 3/8" drill bit, ratchet, socket set, tape measure and marker.
Yes. Hardware is not included. You must purchase your own hex bolts, flat washers, lock washers and nuts to secure the mounting brackets to the truck bed.
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.
1. Push the tank up to the truck cab and center it side-to-side, ensuring it is fully supported by the truck bed floor. Use the mounting brackets as a guide to mark hole locations. 2. Remove the tank and drill 3/8" holes in the marked locations. 3. Place the tank back in the bed and align the drilled holes with the mounting brackets. Ensure the tank is level. 4. Secure the mounting brackets with a hex bolt, two flat washers, one lock washer and one nut in each hole. Do not over tighten. 5. Attach the filler neck and cap.
You must drill 3/8" holes in the truck bed floor at the locations marked by the mounting brackets.
No. Do not cut, weld or drill into the tank. Doing so could result in serious injury or death.
Use the following torque specifications when securing the mounting brackets: M6 bolt: 3 ft-lbs; M8 bolt: 7 ft-lbs; M10 bolt: 16 ft-lbs; M12 bolt: 28 ft-lbs. For SAE fasteners: 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. These are general guidelines; if purchasing hardware, use the torque specifications provided with that hardware.
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.
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, which is not provided with the tank.
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.
No. The tank must be lifted only when empty.
The tank is for private use only. It is not intended to be used commercially.
No. The tank does not meet the code of federal regulations title 49 (chapter iii [393.65, 363.67]) and is not to be used as an auxiliary tank.
The transfer tank 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.
Ensure the tank is level before final tightening. 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. Do not interfere with factory-installed safety equipment.
Never exceed the vehicle manufacturer's recommended capacity.
Yes. You must drill 3/8" holes in the truck bed floor at locations marked by the mounting brackets. Before drilling, check under your vehicle to ensure the drill location does not puncture brake lines, fuel lines, electrical wires or fuel tanks.
You must purchase hex bolts, flat washers, lock washers and nuts. Each mounting bracket hole requires one hex bolt, two flat washers, one lock washer and one nut.
No. The tank is DOT-compliant for Class 3 combustible fuels (diesel) only. It is not approved for gasoline and should never be connected to a vehicle's fuel system or used as an auxiliary fuel tank.
Torque depends on bolt size. For example: 1/4" bolt: 3 ft-lbs; 5/16" bolt: 7 ft-lbs; 3/8" bolt: 16 ft-lbs; 1/2" bolt: 28 ft-lbs. Use the torque specifications provided with your hardware if different.
The tank must be grounded to prevent static explosion. You must use an automatic shut-off nozzle and a fuel filter. The tank must be vented at all times and never pressurized. It must be lifted only when empty. Do not exceed the vehicle manufacturer's recommended capacity.
