Part Type: TRANSFER TANK
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. This particular transfer tank is a combination unit, meaning it has a built-in truck tool box to keep your equipment and valuables safe, well-organized and easily accessible whenever needed. The tool box is constructed from extra-thick aluminum for increased structural strength and is welded together into a single piece. The lid features a patented RigidCore foam-filled design, sandwiched between two aluminum plates. This greatly increases lid strength and helps prevent bending and warping. The locking mechanism of this transfer tank tool box provides excellent security for your items, featuring stainless steel, key-operated paddle handles. Stainless steel construction supplies the locks with long-lasting corrosion resistance, and they feature an internal connecting rod that allows the lid to be opened from either side of the truck. 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.

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.
Hardware is not included with the tank. You must purchase hex bolts, flat washers, lock washers, and nuts for each mounting hole. The manual specifies one hex bolt, two flat washers, one lock washer, and one nut per hole. If any holes fall between the ribs on the truck bed floor, spacers will also be required.
Yes. 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.
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 holes. 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 to the truck bed with one 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.
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. Before securing, ensure the tank is level.
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. Spacers are not included and must be purchased separately.
Drill 3/8" holes in the marked locations where the mounting brackets will attach to the truck bed floor.
No. Do not cut, weld or drill into the tank. Doing so could result in serious injury or death.
Yes. Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion.
The manual provides general torque guidelines. For hex bolts, use the torque specification that matches the bolt size you purchase. General guidelines are: M6/1/4" bolt = 3 ft-lbs, M8/5/16" bolt = 7 ft-lbs, M10/3/8" bolt = 16 ft-lbs, M12/7/16" bolt = 28 ft-lbs, and 1/2" bolt = 28 ft-lbs. If purchasing hardware, use the torque specifications provided with that hardware. Do not over tighten.
Make sure the transfer tank and pump are grounded to avoid static charge. Static build-up can result in explosion. The manual does not specify the grounding method or materials required; consult the manufacturer or a qualified installer for proper grounding procedures.
Never use the tank for storing or transporting flammables, explosives, hazardous materials or hazardous waste such as gasoline, solvents, gun powder, dynamite, propane tanks, acetylene tanks or cutting torches. Never pressurize the tank. Never connect it to a vehicle's fuel system or use it as an auxiliary fuel tank. Never cut, weld or drill into the tank. Never exceed the vehicle manufacturer's recommended capacity. Never modify the product. Never use it commercially.

Ensure all knobs, bolts, screws, straps and locks are firmly secured. Ensure the tank is level. Verify that the tank is securely bolted to the bed of the vehicle.
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.
With the transfer tank installed, periodic inspections should be performed to ensure all mounting hardware remains tight. Ensure all knobs, bolts, screws, straps and locks are firmly secured before every trip.
