Transfer Flow's expanded capacity fuel tank is designed to replace the stock tank on 2015 Ford F-250 and F-350 short-wheelbase or long-wheelbase diesel trucks.

For SWB, Transfer Flow offers a 50-gallon tank to replace the stock 26-gallon tank. For LWB crew cab and extended cab pickups, the company offers a 57-gallon fuel tank to replace the stock 37.5-gallon tank.

Transfer Flow's powder-coated black fuel tanks are made from 12- and 14-gauge aluminized steel designed for corrosion resistance and better strength. The tanks are baffled to provide extra support and reduce fuel slosh. The tanks come with new straps and mounting hardware. There's an optional polymer spray-on coating for a more durable finish.
