When your operation demands maximum fuel capacity without sacrificing truck bed functionality, the WEATHER GUARD Model 352-3-02 Steel Transfer Tank delivers professional-grade performance in a 75-gallon configuration. This substantial automotive accessory goes beyond standard 50-gallon tanks, dramatically reducing refueling trips and extending your operational range for diesel fuel and hydraulic fluid transport. Engineered with the same intelligent L-shaped design that integrates seamlessly with WEATHER GUARD Gull Wing Boxes and Saddle Boxes, this heavy-duty transfer tank is specifically sized for full-size pickup trucks where payload capacity and bed dimensions can accommodate the increased volume. For contractors, landscapers, equipment operators, and commercial fleets running demanding schedules with substantial fuel consumption, this 75-gallon capacity represents a game-changing upgrade that keeps operations running efficiently while minimizing costly downtime for fuel stops.
75-Gallon Capacity: Maximum Range for Demanding Operations
The 75-gallon capacity of this transfer tank represents a 50% increase over standard 50-gallon models—a substantial difference that translates directly into operational advantages for high-volume fuel users. If you're running multiple pieces of equipment throughout long workdays, servicing remote job sites far from fuel sources, managing large landscaping crews with numerous mowers and equipment, operating construction machinery with significant fuel consumption, or simply want to minimize the frequency of refueling trips that cut into productive work time, this additional 25 gallons provides meaningful benefits that compound over weeks and months of operation.
Consider the practical impact: If your equipment consumes 50 gallons per day across all machines, a 50-gallon tank requires daily refilling. The 75-gallon tank provides a day and a half of operation from a single fill, or allows you to fuel multiple additional pieces of equipment before needing to replenish your supply. This extended capacity means fewer trips to fuel stations or bulk suppliers, less time spent on fuel management instead of revenue-generating work, reduced fuel transportation costs over time, and greater flexibility in scheduling and route planning since fuel availability becomes less of a constraint on your daily operations.
The L-shaped configuration maintains the intelligent space utilization that makes these tanks so popular with professional operators. Designed specifically for full-size pickup trucks, the tank wraps around your existing WEATHER GUARD toolbox setup—whether you're running Gull Wing Boxes or Saddle Boxes—allowing both secure tool storage and substantial fuel transport capability to coexist in your truck bed. At approximately 43 inches long, 30 inches wide, and 26 inches high, the tank is sized to take advantage of full-size truck bed dimensions while still leaving usable bed space for other cargo, equipment, or materials that your operation requires.
Commercial-Grade Steel Construction for Heavy-Duty Service
The WEATHER GUARD 75-gallon Transfer Tank is constructed from heavy-duty 12-gauge steel panels throughout—the same commercial-grade material thickness used in smaller capacity tanks, but engineered into a larger structure designed to handle the increased weight and stresses of 75 gallons of fluid. This isn't a compromise or a consumer-grade tank scaled up; it's purpose-built equipment engineered specifically for the rigors of professional operations where 75 gallons of diesel or hydraulic fluid (weighing over 500 pounds when full) must be transported safely and reliably across thousands of miles and countless job sites.
The overlapping edge panel design provides superior corner support—particularly critical in larger capacity tanks where the forces involved with fluid movement and structural loading are proportionally greater. Corners remain the most vulnerable points in any tank construction, and WEATHER GUARD's overlapping design creates exceptionally robust joints that maintain structural integrity even under the substantial stresses inherent in transporting this volume of fluid. This engineering attention to structural weak points translates directly into extended service life and reliable performance through years of demanding commercial use.
Interior baffles are strategically positioned throughout the tank's larger interior volume to minimize fluid motion during transport. With 75 gallons of liquid, the potential for problematic sloshing effects is significantly greater than in smaller tanks—more mass means more momentum, more force during acceleration and braking, and more stress on tank structures. The baffles break up these large fluid movements, reducing stress on the tank walls and welds, extending tank life by preventing fatigue at critical structural points, and contributing to more stable, predictable vehicle handling. Proper baffling in a 75-gallon tank isn't optional—it's essential for safe operation and long-term reliability.

Safety and Operational Features for High-Capacity Transport
Safety becomes even more critical when transporting larger fuel volumes, and the WEATHER GUARD 75-gallon Transfer Tank incorporates robust features specifically engineered for safe high-capacity operation. The vented filler cap prevents dangerous pressure build-up inside the tank as temperatures fluctuate throughout the day—particularly important with larger volumes where thermal expansion effects are more pronounced. As 75 gallons of diesel or hydraulic fluid heats up and expands, or as elevation changes during transport, the vented cap allows air to enter or escape as needed, preventing pressure accumulation that could damage the larger tank structure or create hazardous conditions. The lockable feature provides security for your substantial fuel investment—75 gallons represents significant value that needs protection against theft or tampering at job sites, customer locations, or overnight storage.
Rubber isolation bushings serve as critical interfaces between the heavy tank and its mounting points, absorbing road vibration and protecting the tank structure from constant stress. With the increased weight of a 75-gallon capacity tank—175 pounds empty and over 675 pounds when full with diesel—these isolation bushings become even more important for preventing vibration-induced fatigue at mounting points and weld seams. They act as shock absorbers that protect your investment and extend service life by preventing the accelerated wear that could occur if the substantial mass of the full tank was rigidly mounted directly to the truck bed.
The reinforced filler neck is engineered to withstand the increased frequency and duration of filling operations required for a 75-gallon tank. Filling 75 gallons takes longer than filling 50, meaning more time with fuel nozzles or pump equipment engaged with the filler neck, and this reinforcement ensures the high-use area maintains its integrity and seal through thousands of filling cycles. The 2-inch standard NPT (National Pipe Thread) connection accommodates most commercial pumps and transfer equipment, including higher-flow pumps that operators often use with larger capacity tanks to reduce filling time.
The 1/4-inch drain port is positioned for routine maintenance and complete tank drainage. Regular maintenance is particularly important with larger capacity tanks where any water condensation or sediment has more volume in which to accumulate. The accessible drain port makes periodic draining straightforward, helping maintain fuel quality and tank condition over years of service. Complete drainage capability is also essential when the tank needs cleaning, inspection, or service.
Professional Finish and Quality Assurance
The Brite White ARMOR TUF powder coat finish provides commercial-grade protection engineered for the harsh environments that transfer tanks face. This tough, chip-resistant, corrosion-proof coating protects the substantial steel structure from moisture, road salt, chemicals, UV exposure, and the inevitable impacts that occur in professional truck bed environments. The bright white color maintains a professional appearance, improves visibility of the tank for safety considerations, makes it easier to spot leaks or damage during routine inspections, and reflects heat to help keep fluid temperatures more stable—particularly beneficial with the larger volume where temperature management becomes more significant.
The Limited Lifetime Warranty demonstrates WEATHER GUARD's confidence in the construction quality and durability of this high-capacity transfer tank. USA manufacturing ensures quality control standards, material specifications, welding procedures, and construction methods that meet the demanding requirements of professional operators transporting substantial fuel volumes daily.
Important Usage Guidelines
WEATHER GUARD Transfer Tanks are designed specifically for non-flammable fluids such as diesel fuel and hydraulic oil. These tanks are NOT approved for gasoline or other flammable fluids—using them for such purposes would be dangerous, illegal, void all warranties, and create serious safety hazards. The higher flash point of diesel and hydraulic fluids (compared to gasoline) makes them appropriate for the tank designs, venting systems, and mounting methods used in these products.
These transfer tanks are standalone fluid transport and storage solutions—NOT designed to be connected to your vehicle's primary fuel system as an auxiliary tank. The tank transports fuel to equipment, generators, or machinery at job sites, or stores hydraulic fluid for equipment maintenance. This distinction is important for safety and regulatory compliance.
