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 100-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 100-gallon steel transfer tank comes with a white 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 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 for storing or transporting explosives, hazardous materials, propane tanks, acetylene tanks, cutting torches or other hazardous waste.
Yes. You must drill 3/8" holes in the truck bed floor using the mounting brackets as a guide. 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.
Required tools are: drill, 3/8" drill bit, ratchet, socket set, tape measure and marker.
You must purchase hex bolts, flat washers, lock washers and nuts for each mounting hole. The manual does not specify the quantity or size of bolts required, so consult your dealer or the product documentation for your specific tank model.
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.
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.
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. Ensure the tank is level before securing.

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.
The tank is not compatible with diesel exhaust fluid (DEF) or other corrosive materials. Do not use 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.
