Check of fuel system

 Gasoline is extremely flammable therefore during the work with any components of fuel system it is necessary to take special precautionary measures. Do not smoke, and do not come nearer to a venue of works with naked flame or the carrying unprotected by the lamp shade. Do not perform such works in the garages equipped with the heating devices working at natural gas (such as vodogre, dryers, etc.). The working platform has to be ventilated well. At hit of gasoline on skin immediately wash away it water with soap. When carrying out any works with fuel system put on goggles and hold near at hand the fire extinguisher. In case of a gasoline spillage immediately wipe a pool, but do not keep the rags impregnated with gasoline in places where it can self-ignite.   |

-  If you felt a gasoline smell during the movement or after the car stood on the sun, it is necessary to check a condition of all fuel system immediately. 
 
-  Uncover a fuel tank and check it for existence of damages and corrosion. Sealing laying on a cover has to be whole. In case of existence of damages or corrosion replace a cover. 
 
-  Survey inlet and returnable lines of fuel system on existence of cracks. Make sure that connections between lines of fuel system and system of injection of fuel, and also between lines of fuel system and the built-in fuel filter did not weaken. 
 
 
-  As some components of fuel system - for example, a fuel tank and some lines of fuel system - are in the lower part of the car, it is easier to examine them when the car is raised by the winch. If it is impossible, the car and install to a poddomkratta it on support. 
 
-  On the raised car examine a fuel tank and a bulk mouth on existence of holes, cracks and other damages. Pay special attention to a condition of connection between a bulk mouth and a tank. Sometimes leak of fuel happens owing to weakening of collars of fastening of a rubber mouth or because of mouth material damage. Examine all arms and tapes of fastening of a fuel tank to make sure that it is reliably strengthened on the car.

 Never, under no circumstances, try to repair a fuel tank (excepting replacement its rubber a component). The flame of the welding machine or any other naked flame can easily lead to explosion of evaporations of gasoline in a tank.   | 
 
 
-  Carefully check all fuel hoses and metal lines going from a tank for existence of the weakened connections, twisting, signs of wear of materials of hoses and other damages. If necessary make repair or replace the damaged sections.
