DOT-Compliant Fuel Transfer Eliminates Compliance Risk

DOT-Compliant Fuel Transfer Eliminates Compliance Risk

A single compliance failure on the road can mean fines, forced downtime, and cleanup costs that destroy your operating margin. This Transfer Flow refueling tank is Department of Transportation legal to carry and transfer gasoline, diesel, methanol, ethanol, and kerosene — so you stay compliant without second-guessing. The 12-gauge ReliaSteel high-yield U.S. aluminized steel construction eliminates the weak weld failures that plague inferior tanks. This curated unit is built tough and powder coated black for a durable satin finish that resists corrosion in real-world conditions.

L-Shape Design Maximizes Bed Space Without Sacrificing Capacity

L-Shape Design Maximizes Bed Space Without Sacrificing Capacity

Most over-the-rail tool boxes eat into your fuel storage options. This L-shaped refueling tank solves that problem by fitting beneath standard tool box configurations while still holding a full 100 gallons of extra fuel. That is enough capacity to keep equipment running through multi-day jobs or extended off-grid adventures without detours to fuel stations. The industrial-strength 12-gauge ReliaSteel build means you are not trading structural integrity for space efficiency. Product dimensions include three inches in length and width for mounting brackets and three inches in height for the filler neck, so plan your bed layout accordingly.

Hose-Purge System Protects Your Truck Bed From Fuel Spills

Hose-Purge System Protects Your Truck Bed From Fuel Spills

Residual fuel left in a transfer hose does not just create mess — it degrades your truck bed coating and creates a slipping hazard for anyone climbing in. The hose-purge feature on this Transfer Flow system lets you pull any fuel remaining in the hose back into the refueling tank after each use. That eliminates puddles in the bed and stretches your usable fuel capacity further by recovering what would otherwise be wasted. The included 12-volt GPI fuel pump delivers reliable flow, and an optional methanol pump is available for specialized applications. This investment protects both your equipment and your workspace.

Compatibility Check

This L-shaped tank is engineered to fit under most over-the-rail tool box setups. Verify your bed dimensions before ordering.

  • Truck bed accommodates over-the-rail tool box configuration
  • Account for 3" additional length and width for mounting brackets
  • Account for 3" additional height for the filler neck

★★★★★
“Had a thin-wall aluminum tank crack on us during a winter run — cost us two days and a cleanup bill. Switched to this Transfer Flow L-shape and the ReliaSteel build is noticeably heavier duty. Fits right under our existing tool box, and the hose-purge feature keeps the bed clean. DOT compliance paperwork was straightforward for our annual inspection. This is the tank we should have bought the first time.”
