The Transfer Flow Replacement Fuel Tanks for 2015 Ford trucks offer users options for increased fuel capacity. Designed for 2015 Ford F250/F350 models, a 50-gal fuel tank is offered to replace the 26-gal tank that comes stock on SWB crew cab pickups. For the LWB crew cab and extended cab pickups, a 57-gal fuel tank is available to replace the stock 37.5-gal tank. The fuel tanks are made from 12- and 14-gauge aluminized steel for corrosion resistance and strength, are baffled for extra support and to reduce slosh and come with straps and mounting hardware. The tanks are powdercoated black with an optional high-end polymer spray-on coating.
