Designed to fit full-size, American-made pickups, the 325 and 425 sizes have low profiles for better rear vision. They feature fill openings offset to the side of the tank for safety and easy access. A tough circular design adds strength. The 210 gallon tank fits both mini pickups and full-sized models. Depending upon which way the tank is turned, the bottom width can be either 39 in or 48 in.Our pickup truck tanks feature built-in, graduated gallon indicators and slosh-proof lids. An installed bulkhead fitting is standard in the pickup truck tanks.
