How to Deal with Fuel Tank Cap Leakage?
2 Answers
Solutions for fuel tank cap leakage include: 1. Soap or chewing gum: If the fuel tank is damaged and the leakage is minor, clean the leaking area and apply soap or chewing gum to temporarily seal it. Using epoxy resin adhesive for repair yields better results. 2. Pull over: In cases of significant leakage, ensure there are no open flames inside the vehicle. Pull over the moving car, turn off the engine, and do not rush to call for help. After all passengers exit the vehicle, open the doors, move to the roadside far from the car, and confirm safety before calling for maintenance. 3. Place warning signs: Set up warning signs behind the car to alert passing vehicles to detour. On regular roads, warning signs should be placed 50-100 meters away, while on highways, they should be placed 150 meters away.
I was really startled when I discovered the fuel tank cap was leaking last time, with obvious oil stains below the filler neck. I immediately wiped the leaking area clean with an old towel to prevent sparks from causing danger. Typically, such issues are either due to a cracked or aged sealing ring or the fuel tank cap not being tightened properly. I checked the cap first and sure enough, the rubber gasket had hardened like a plastic sheet, completely losing its elasticity. A temporary fix could involve wrapping some plumber's tape as an emergency measure, but it's best to replace the sealing ring immediately. If you smell a strong gasoline odor after parking, there might be an issue inside the fuel tank, and you should head to the repair shop for inspection right away. Never use a plastic bag to seal the cap, as vapor buildup could lead to bigger problems.
