Understanding Different Types of Fuel Tanks

Main Fuel Tank
TheMain Fuel Tankis the primary storage container for your vehicle's fuel. Located typically underneath the vehicle, it's designed to safely store gasoline or diesel fuel and supply it to the engine. Most passenger vehicles have a main fuel tank capacity between 12-15 gallons for compact cars and up to 30+ gallons for larger SUVs and trucks.
Auxiliary Fuel Tank
AnAuxiliary Fuel Tankis a secondary fuel storage system that supplements your main tank. These tanks are often aftermarket additions that provide extended driving range without refueling. They're particularly popular among long-haul trucks, off-road vehicles, and work trucks that need additional fuel capacity for remote operations.
Saddle Tank
ASaddle Tankis a specially designed fuel tank that's shaped like a horse saddle, straddling another component of the vehicle (usually the driveshaft). This design maximizes fuel capacity while working around the vehicle's existing architecture. Commonly found in larger trucks and commercial vehicles, saddle tanks often come in pairs, one on each side of the vehicle.
Transfer Tank
ATransfer Tankis a portable fuel storage container typically mounted in the bed of a pickup truck. Unlike other fuel tanks, it's not connected to the vehicle's fuel system. Instead, it's used to transport fuel to other vehicles or equipment at job sites. These tanks often include pumping systems for easy fuel transfer.
Day Tank
ADay Tankis a smaller intermediate fuel tank that supplies fuel to engines or generators for daily operation. While not common in passenger vehicles, they're essential in industrial applications and backup power systems. Day tanks typically include fuel filtration systems and are automatically refilled from a main storage tank.
Reserve Tank
AReserve Tankis a small additional fuel tank that provides emergency fuel when the main tank runs empty. In modern vehicles, this is often integrated into the main tank design, giving you those extra few miles when your fuel gauge reads empty. This safety feature helps prevent complete fuel exhaustion on the road.
Note: All fuel tanks must meet strict safety standards and should only be installed by qualified professionals. Proper installation and maintenance are crucial for safe operation.
