45 Gallon Ford Transit 250, 350 and 350HD Van Midship Replacement Fuel Tank

Extend Your Range with a 45-Gallon Ford Transit Replacement Fuel Tank

Tired of planning your trips around fuel stops? Upgrade your Ford Transit with our 45-gallon high-capacity replacement fuel tank and spend more time on the road and less time at the pump. Whether you drive a Class B motorhome, cargo van, passenger van, or cutaway chassis, this premium replacement tank provides the extended driving range and confidence you need for every adventure.

Engineered specifically for 2021–2026 Ford Transit 250, 350, and 350HD models equipped with the 3.5L EcoBoost engine, this 45-gallon replacement tank increases fuel capacity by approximately 45% over the factory 31-gallon tank. The result is fewer fuel stops, greater travel flexibility, and enhanced convenience for long-distance driving.

Constructed from heavy-duty 12-gauge U.S. aluminized steel, this tank is built to withstand years of demanding use while providing superior corrosion resistance. Internal baffles minimize fuel slosh for improved vehicle stability and comfort. Designed as a direct-fit replacement, the tank installs in the factory location above the rear differential and securely mounts within the frame rails.

For added peace of mind, the fuel tank system has been tested to meet strict emissions requirements and is 50-state legal for gasoline-powered vehicles. It is covered by a California Air Resources Board (CARB) Executive Order, ensuring nationwide regulatory compliance.

A Strap Kit is required for installation and must be purchased separately.
