According to tips from car experts, you should always wear protective eyeglasses when performing the above steps. Other protective equipment may be used if needed such as gloves and safety shoes.

In addition, gasoline is very flammable, so:

  • Always keep a fire extinguisher on the side when you operate and work with the fuel system.
  • Avoid smoking or putting flammable materials near your car, especially near the fuel tank.
  • Do not use any incandescent lamp in any circumstances because the heat generated on the bulb's outer glass is also a serious risk of burning the fuel.
  • Be cautious with electrical tools that can ignite the fuel.
