Fuel tanks are designed to keep your engine's fuel clean, vented and secure on all lawn mowers, snow blowers and outdoor power products. If you spot debris in the gas tank or leaking gasoline, it's time for fuel tank maintenance. Never attempt to repair a damaged tank. It poses a risk of leakage, fire or fuel contamination. If you're replacing a fuel tank, use only parts recommended by the engine manufacturer. These parts will attach securely to your engine in the space provided.
Many fuel tanks are designed to use a vented gas cap to prevent a vacuum or pressure from forming in the fuel system. If fuel is leaking from the cap, a properly fitted replacement cap can solve the problem.
