Warning! Gasoline is highly flammable. Therefore, when working with any part of the fuel system, additional precautions should be taken. Do not smoke or allow open flames or unshielded lights near the work area. Do not work in areas where gas-powered appliances are present (for example, water heaters or clothes dryers). Since gasoline is a carcinogen, try to avoid fuel coming into contact with exposed areas of the body. Wear fuel-resistant gloves. If fuel comes into contact with your skin, wash the affected area immediately with soap and water. Wipe up any spilled fuel immediately and do not store fuel-soaked rags in places where they could catch fire. The fuel system is under constant pressure. Therefore, before disconnecting the fuel lines, be sure to first relieve the fuel pressure in the system. Wear safety glasses when performing any work on the fuel system. Always keep a class B fire extinguisher on hand.
1. If you smell fuel while driving or after the vehicle has been in the sun, inspect the fuel system immediately.
2. Remove the fuel filler cap and inspect it for damage and corrosion. The gasket should not be damaged. If the gasket is damaged or shows signs of corrosion, remove it and install a new one (see paragraph 18).
3. Inspect the fuel supply and return lines for cracks. Make sure the union nuts used to secure the fuel lines are securely tightened. fastening metal fuel lines to fuel injection system components, and hollow bolts used in "banjo" type fittings (on the linear fuel filter).
4. Since some components of the fuel system, such as the fuel tank and the fuel supply and return lines, are located underneath the vehicle, they are easier to inspect after the vehicle is raised on a lift. If this is not possible, raise the vehicle and support it securely.
5. On a raised vehicle that is not supported by reliable supports, inspect the fuel tank and filler neck for punctures, cracks and other damage. The connection between the filler neck and the tank plays a particularly important role. Sometimes the rubber filler neck leaks due to loose clamps or aging rubber. As a rule, the car enthusiast can fix these problems himself.

Warning! Do not attempt to repair the fuel tank under any circumstances (excluding rubber elements). A welding torch or any open flame can easily cause the fuel vapors inside the tank to explode.
6. Carefully inspect all rubber hoses and metal lines coming from the fuel tank. Check for loose connections, damaged hoses, flattened lines and other damage. Carefully inspect the lines coming from the tank to the fuel injection system. If necessary, repair or replace damaged sections (see chapter 4).
