Attention! Observe fire safety regulations when performing maintenance on the fuel system. On vehicles with injection engines, disconnect any hoses after performing decompression measures.
1. The fuel system is best checked when the vehicle is hoisted or placed on jackstands to allow access to parts from the underside and make the job as easy as possible.
2. If you smell gasoline while driving or after parking your car in the sun, the fuel system needs to be inspected immediately.
3. Check, being under the car, a condition of a tank and a pipe of a mouth. Especially carefully inspect the connection of the neck with the tank. The presence of punctures, cracks and mechanical damage is not allowed.
4. Carefully inspect all rubber hoses and tubes extending from the tank. Check the connections for signs of wear, pinching or other damage on the hoses. Especially carefully check the condition of the vent pipes and hoses of the tank, which often wind around the neck and are pinched or clogged. Track the condition of the hoses along their entire length, to the front of the car. Replace damaged sections of pipelines.
5. If after the checks you still smell gasoline, check the vapor recovery system (see subsection 5.13).
