Construction of fuel lines

One end of the fuel tank hose is connected to the fuel tank, and the other one, to the functional components of the fuel system. This may be: the filler neck, or the fuel filter. Joints air tightness is ensured with metal clamps.

fuel lines have no certain service life. To make them serve for as long as possible, during the installation ensure reliability of the connections, and make sure hoses are not in contact with other components of the fuel system and body. fuel lines are to be inspected after every 100000 operational kilometers.
