Increase driving range on 2011-2016 Ford F-250, F-350, and F-450 6.7L Powerstroke crew cab long bed trucks with S&B's 70-gallon midship replacement tank. It replaces the factory 35-gallon tank, reuses the OE sending unit, and includes replacement straps for a clean factory-style installation. The tank is compatible with gooseneck and 5th wheel towing setups and is transfer-pump ready through the embedded 1/2-inch NPT fitting. Notes: it sits about 3 inches lower than the OE tank shield, is not compatible with the OE skid plate, high-flow truck-stop nozzles may not shut off automatically, and auxiliary tanks may affect S&B warranty coverage.
