Premium 6.7 Powerstroke Replacement Fuel Tanks & High-Capacity Upgrades
For diesel truck owners who rely on their 6.7L Ford Powerstroke for long-distance towing, hot shotting, or remote overland travel, fuel capacity is often a major limiting factor. Factory midship fuel tanks—especially on short-bed configurations—can be frustratingly small, forcing you to plan your routes entirely around frequent, inconvenient fuel stops. Upgrading to a premium 6.7 Powerstroke replacement fuel tank allows you to nearly double your truck's onboard fuel capacity, dramatically extending your driving range and giving you the freedom to bypass expensive highway fuel stations in favor of better high-flow diesel prices.
Our specialized selection features high-capacity replacement tanks engineered specifically for the 2011–2026 platform from industry-leading manufacturers like S&B Tanks and Titan Fuel Tanks. These heavy-duty tanks are constructed from high-density, cross-linked polyethylene (XLPE), a military-grade polymer that is virtually indestructible, corrosion-proof, and significantly lighter than steel. Designed as direct-fit replacements, these midship tanks utilize the unused space beneath your truck's chassis, sitting lower and contouring around structural obstacles without compromising ground clearance or interfering with your factory driveshaft and suspension components.
Installing a high-capacity replacement tank is a seamless process that retains your factory fuel sending unit, fuel lines, and float assembly. After installation, updating your truck's computer parameters with an electronic programmer or calibration tool allows your dashboard's "Distance to Empty" (DTE) readout to accurately reflect your massive new fuel capacity. Whether you are hauling a massive fifth-wheel trailer across state lines or building a rugged work truck, a heavy-duty replacement tank provides the ultimate convenience and range. Browse our selection of year- and cab-specific fuel tanks, and rely on the team at Full Force Diesel to help you go further between fill-ups.
