How to Replace a Broken Fuel Tank Cap?
2 Answers
Use tools to push out the two retaining pins at the end connected to the fuel tank cap, then pull off the fuel tank cap tether. Insert one end of the new tether into the fuel tank cap loop position, push the retaining pins into the eyelets, and then squeeze to align them. Finally, screw the fuel tank cap with the tether onto the fuel tank, and secure the other end to the vehicle body.
Last time my fuel tank cap broke, I thought replacing it myself would be pretty straightforward. The steps are super simple: first, turn off the engine and engage the handbrake for safety; then clean around the fuel filler neck to avoid any debris falling in; if the old cap is broken plastic, you can carefully use pliers to remove the fragments, but don’t apply too much force to avoid damaging the filler neck; next, buy a new cap—check your car model online or ask at an auto parts store to ensure you get the right one, as some are universal but need to match the sealing ring; when installing, make sure your hands are dry, then tighten it clockwise until you hear a click to ensure a proper seal; after replacement, start the car and listen for any hissing sounds—if everything sounds normal, you’re good to go. It’s a good idea to wear gloves to prevent static and save money while honing your DIY skills—the whole process takes about ten minutes. Don’t forget to check the cap for wear and replace it periodically, otherwise fuel evaporation can cause unpleasant odors and increase fuel consumption!
