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 75-gallon steel L-shaped 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 75-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 bolts, washers, nuts and spacers 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. The tank is also not compatible with diesel exhaust fluid (DEF) or other corrosive materials.
Yes. The tank and mounting brackets are supplied, but all fasteners must be purchased separately. You will need hex bolts, flat washers, lock washers and nuts for each mounting hole. The manual recommends using a 3/8" drill bit to create mounting holes, which suggests 3/8" bolts are appropriate, but confirm the exact size and quantity with your dealer or the mounting bracket specifications.
You will need: a drill, 3/8" drill bit, ratchet, socket set, tape measure, and marker. The manual rates installation difficulty as Easy.
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. Take precaution that all fasteners near the fuel tank do not create the possibility of fuel tank puncture or other damage during a collision. The manual emphasizes this is a critical safety step.
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 hole locations. Before securing, ensure the tank is level.
Drill 3/8" holes in the truck bed floor at the locations marked by the mounting brackets.
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.
Yes. Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion.
Secure the mounting brackets to the truck bed with a hex bolt, two flat washers, one lock washer and one nut in each hole. Do not over tighten the hardware. These fasteners are not included and must be purchased separately.
The manual provides general torque guidelines. For a 3/8" bolt (likely size for 3/8" holes), the specification is 16 ft-lbs. For a 1/2" bolt, it is 28 ft-lbs. However, the manual states: 'If purchasing hardware use the torque specifications provided with that hardware.' Always follow the torque specifications that come with your purchased fasteners, as they may differ from these general guidelines.
The manual states to 'Attach the filler neck and cap' in Step 2 but does not provide detailed attachment instructions. Consult your dealer or the filler neck assembly instructions for specific attachment procedure.
The manual warns: 'Make sure the transfer tank and pump are grounded to avoid static charge. Static build-up can result in explosion.' However, the manual does not provide specific grounding procedures or wire routing details. Consult your dealer or a qualified technician for proper grounding installation.
No. The tank should never be connected to a vehicle's fuel system or used as an auxiliary fuel tank. The tank does not meet the code of federal regulations title 49 (chapter iii [393.65, 393.67]) and is not approved for this use.
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. Additionally, the tank must be vented at all times, and you must remove the vent cap with caution.
You must use an automatic shut-off nozzle (not provided) and a fuel filter (not provided). 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. The manual does not specify a maximum weight capacity for lifting.
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.
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.

Yes. You must drill 3/8" holes in the truck bed floor at locations marked by the mounting brackets. Before drilling, check underneath the vehicle to ensure you do not puncture brake lines, fuel lines, electrical wires or fuel tanks.
For 3/8" bolts, use 16 ft-lbs; for 1/2" bolts, use 28 ft-lbs. However, always follow the torque specifications provided with your purchased hardware, as they may differ from these general guidelines.
