Compliance-Ready Diesel Storage That Eliminates Regulatory Risk

Compliance-Ready Diesel Storage That Eliminates Regulatory Risk

A compliance failure or failed weld on a diesel tank doesn't just cost money — it triggers fines, environmental cleanup, and operational downtime that derails your entire fleet schedule. This Transfer Flow tank is built tough from 14-gauge aluminized steel, a material specifically chosen for superior corrosion resistance under daily fuel exposure. The tank is legal to carry diesel fuel on the road, so you avoid the regulatory exposure that comes with uncertified alternatives. Every unit is vetted through Transfer Flow's durability testing process, ensuring the welds and structure hold up under real-world conditions rather than just looking adequate on a spec sheet.

Engineered Stability For Safe Fuel Transport

Engineered Stability For Safe Fuel Transport

Fuel sloshing inside a transfer tank isn't just an annoyance — it shifts weight dynamically, affecting vehicle handling and putting stress on mounting points over time. This tank incorporates two internal baffles designed to control fuel movement during transit, keeping the liquid mass stable whether you're on highway stretches or uneven job site terrain. The baffles work alongside the powder-coated black exterior finish, which adds a second layer of protection against the elements. This curated design respects your investment by extending the functional lifespan of both the tank and your truck bed, reducing the wear that unprotected tanks inflict on mounting hardware.

Pump-Specific Compatibility Protects Your Warranty

Pump-Specific Compatibility Protects Your Warranty

Using the wrong fuel pump on a transfer tank voids warranties and creates liability — a risk most buyers don't discover until something fails. This tank is engineered specifically for GPI and Fill-Rite 15-GPM refueling pumps, and the warranty is contingent on using one of these two options. Tank Vault lists this requirement upfront because hidden warranty exclusions are exactly the kind of surprise that costs fleet managers thousands. The included mounting kit and installation instructions ensure a straightforward setup when paired with the correct pump. Available in 50 gallon and 80 gallon capacities, you can match the tank size to your actual fuel demand without overpaying for unnecessary volume.

Compatibility Check

Confirm these requirements before ordering to ensure proper fit and warranty coverage.

  • Truck bed length accommodates 54 inches minimum for 50-gallon tank
  • Mounting area supports filled tank weight with included mounting kit
  • GPI or Fill-Rite 15-GPM refueling pump available for installation

“Mounted the 50-gallon in our F-250 last month. The baffles make a noticeable difference on rough job site roads — no more fuel surge throwing the truck around. Build quality is exactly what you'd expect from Transfer Flow. Paired it with the Fill-Rite pump and had zero issues.”
