Replacing the Fuel Filter — Petrol Models (Opel Astra G)

Remember that gasoline is a highly flammable liquid! When working with fuel system components, observe all accepted fire safety measures. Do not smoke! Do not approach the work site with an open flame or an unprotected portable lamp! Do not service the system in rooms equipped with heating devices operating on natural gas and equipped with a pilot torch (such as water heaters and clothes dryers). Do not forget that gasoline is a carcinogen, i.e., a substance that promotes the development of cancer! Try to avoid fuel coming into contact with exposed areas of the body - use rubber protective gloves, in case of accidental unexpected contact with fuel, wash your hands thoroughly with warm water and soap. Immediately collect spilled fuel and do not store fuel-soaked rags near open flames. Remember that the fuel system of models equipped with fuel injection is constantly under pressure. Before disconnecting the fuel lines, release the residual pressure in the system. When servicing fuel system components, wear protective glasses. Always keep a class B fire extinguisher at hand!
