It will click when it is fully tightened. Push the fuel door closed. RWARNING If you lose the fuel cap, replace it with a Motorcraft or equivalent fuel cap. If you do not use the proper fuel cap, the pressure in the fuel tank can damage the fuel system or cause it to work improperly in a collision, endangering you and your passengers. NOTE: If you replace your fuel cap with an aftermarket fuel filler cap, the customer warranty may be void for any damage to the fuel tank and/or fuel system. 4. Choosing the Right Fuel Use only UNLEADED FUEL in your vehicle. Using leaded fuel is prohibited by federal law. Your warranty may not apply if your vehicle is damaged because you used the wrong fuel. Using a high-quality fuel makes your vehicle more responsive and maintain its good fuel economy and emissions. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use a high-quality fuel. 240
