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 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.

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.
Hardware is not included with the tank. For each mounting hole, you will need one hex bolt, two flat washers, one lock washer and one nut. The manual does not specify the bolt size or quantity of holes, so consult your dealer or the manufacturer for the exact hardware requirements for your vehicle.
The following tools are required: drill, 3/8" drill bit, ratchet, socket set, tape measure, and marker.
Spacers may be required if any mounting holes fall between the ribs on the truck bed floor. The manual does not specify whether spacers are included or must be purchased separately. Consult your dealer if spacers are needed for your installation.
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, etc. 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 using the mounting brackets as a guide to mark the hole locations.
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.
Yes. Treat or seal all fasteners and exposed metal in any holes drilled in the vehicle to prevent corrosion.
Torque specifications depend on the bolt size used. For metric bolts: M6 = 3 ft-lbs, M8 = 7 ft-lbs, M10 = 16 ft-lbs, M12 = 28 ft-lbs. For SAE bolts: 1/4" = 3 ft-lbs, 5/16" = 7 ft-lbs, 3/8" = 16 ft-lbs, 7/16" = 20 ft-lbs, 1/2" = 28 ft-lbs.
