Cleans, seals, and protects metal fuel tanks. Use for tanks up to 8 gal.
Northern Fuel Tank Liner is easy to use and effective when the directions are followed closely. It internally seals the multitude of small leaks that often form due to age, rust or where the straps wrap around the tank. If you fix the major obvious leaks, Northern Fuel Tank Liner seals the rest! Northern Fuel Tank Liner is resistant to gasoline, diesel fuel, alcohol and other fuels or fuel additives. It is designed to seal new or existing fuel tanks with minor leaks. Contrary to what some people will tell you, rust does form inside gas tanks. The cause is condensation and water in the fuel. Northern Fuel Tank Liner seals rust under the liner coating so it cannot flake off to plug fuel-line filters or cause additional damage. Further rusting is also reduced.
