Attention! Gasoline is flammable, so take all precautions when working on any part of the fuel system. Do not smoke or leave open flames or unprotected lamps in the work area, do not work in the garage with appliances and devices powered by natural gas (such as titanium or dryer), if there is a burning wick. If you spill any fuel on your skin, wash it off immediately with soap and water. Wear safety goggles and have a fire extinguisher handy when doing any kind of work on the fuel system. The fuel system is under pressure, so if any lines need to be disconnected, the system must first be depressurized (more information on this subject can be found in chapter 4).
1. The fuel system is easiest to inspect when the vehicle is raised with a lift just enough to allow the parts underneath the vehicle to be visible and accessible.
2. If you smell gasoline while driving or after the car has been in the sun, the system should be thoroughly inspected immediately.
3. Remove the gas tank cap and check it for damage, corrosion, and see if the gasket is damaged (see illustration). Replace plug if necessary.
18.3. Make sure the gas tank cap gasket is (arrow) is not damaged and fits around the entire circumference, otherwise the proper sealing of the fuel system will not occur
4. When the vehicle is raised, check the gas tank and filler neck for punctures, cracks, or other damage. The connection between the filler neck and the tank is especially important. Sometimes the rubber filler neck leaks due to loose clamps or deterioration of the rubber (see illustration).
18.4. Check the fuel filler clamp to make sure it is tight and that there are no cracks or damage to the hose
Attention! Under no circumstances should you attempt to repair the gas tank yourself (except for the replacement of rubber parts). The welding machine and any other open source of fire can immediately ignite gasoline vapors and explode if proper precautions are not taken.
5. Carefully check all rubber hoses and metal pipes coming from the gas tank. Check for loose connections, frayed hoses, kinked metal lines, or other damage. Track how the hoses go to the front of the car along its entire length. Repair or replace damaged areas as needed.
