45 Gallon Ford Transit 350 Van Midship Replacement Fuel Tank
Extend your range and minimize fuel stops with this 45-Gallon Midship Replacement Fuel Tank for the Ford Transit 350 / Transit 250 with OEM 31 gal. fuel tank. Designed as a direct replacement for the factory 31-gallon tank, this high-capacity upgrade provides increased fuel capacity without compromising ground clearance or requiring additional skid plates.
Built from heavy-duty U.S. aluminized steel and powder-coated for long-term protection, the tank is engineered to fit in the same space as the stock unit—mounting securely inside the frame rails above the differential. Internal baffles reduce fuel slosh during cornering or off-road driving, ensuring consistent performance in all conditions. Whether you’re crossing the desert or running a long haul, this tank adds peace of mind and miles between fill-ups.
This 45-gallon fuel tank requires a chassis-specific mounting strap kit. Please add one of the following to your order: Cutaway Strap Kit (Part #0200117295) or Passenger/Cargo Strap Kit (Part #0200117275).
