Many gas tanks are made out of stainless steel. Stainless steel is a durable metal that is resistant to rust and other corrosive factors. With the right cap, stainless steel gas tanks can have an airtight seal that prevents gas vapors from getting out of the tank and into the air. Many people prefer stainless steel tanks over aluminum tanks because stainless steel is more durable and long-lasting. In the world of steel gas tanks, there are several different varieties to choose from.
Carbureted tanks: This rectangular steel tank is the most common form of steel gas tank. The tank has internal baffling, and it has a top feed to make it easy to get the gas in and out of the tank. The tank can attach to the bottom of a vehicle, or be used as a supplemental tank in a vehicle or in a garage.
Sump tanks: Sump tanks are slightly different than carbureted tanks. Sump tanks have a bottom-feed design that makes them ideal for using with high-powered vehicles, such as racing vehicles. These tanks are not recommended for vehicles that use everyday highway and street driving.
Fuel injection tanks: A fuel injection tank allows access to the pump through mounting screws, rather than through a standard lock ring. These tanks can work as stock tanks for fuel pumps. Fuel injection tanks are known for their high performance and reliability under a variety of circumstances.
Vaporworks tanks: Vaporworks tanks are a customized and special tank with a unique design. The tanks use a series of customized ring shapes to close the top of the tank. This helps the fuel remain enclosed until ready for use. The tank comes with an automatically opening and closing valve depending on where the fuel is inside the tank. These tanks are ideal for racing and driving on winding and hilly roads.
