S&B's 62-gallon fuel tank directly replaces the OEM 36-gallon tank without any cutting, drilling, or special modifications. This makes for a trouble-free, faster installation process. S&B's replacement fuel tank holds 5 more gallons than competitor tanks allowing you to save time, go further, and get more out of your truck! S&B Tanks were engineered with a built-in baffled design. This helps to minimize fuel sloshing. This helps to contain fuel around the fuel pick up and prevents unwanted tank sloshing noise.
