Caution! Gasoline is highly flammable, so take all fire safety precautions when working with any part of the fuel system. Do not smoke, use open flames or portable pumps without a protective net. Do not work in a room where there are gas appliances with a "standby" wick (like gas water heaters and dryers). Gasoline is a carcinogenic substance, do not allow it to come into contact with your skin - wear plastic gloves. If gasoline accidentally comes into contact with your skin, wash it off immediately with soap and water. Immediately soak up any spilled gasoline with rags and put the rags in a safe place where there is no risk of them catching fire. Please note that the vehicle's fuel system is always under positive pressure, so always relieve the pressure in the system first before disconnecting any fuel line. Always wear safety glasses when working on the fuel system. Keep a working carbon dioxide fire extinguisher on hand and familiarize yourself with the rules for its use in advance.
1. Before working on any element of the fuel system, it is necessary to relieve the pressure in it.
2. Unscrew the fuel tank filler cap to relieve the pressure in the tank.
3. Remove the fuel pump relay from the engine compartment fuse box (see chapter 12).
4. Start the engine and let it run until it stalls. Then turn it over several times with the starter to ensure that all traces of not only fuel, but also its vapors are removed from the fuel lines. Disconnect the negative cable from the battery (always do this if you are going to work on the fuel system).
Caution: If your vehicle's audio system is equipped with anti-theft protection, make sure you have the unlock code before disconnecting the battery.
5. Now there is no excess pressure in the fuel system.
Note: Before loosening any clamp or removing any fuel line fitting, place a rag around the work area to prevent any spilled fuel from getting on the engine. After completing the work, put the fuel pump relay back in place and connect the negative cable to the battery.
