Check of fuel system

Gasoline is extremely inflammable, therefore at work with any components of fuel system it is necessary to accept special safety measures. Do not smoke, and do not come nearer to a place of work with open fire or the redurable not protected by a lamp shade. Do not make such works in the garages equipped with heating devices, working on natural gas (such, as водогреи, dryers, etc.). The working platform should be ventilated well. At gasoline hit on a skin immediately wash off its water with soap. At carrying out of 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 hold the rags impregnated with gasoline in places where it can самовоспламениться.


  1. If you have felt a smell of gasoline during movement or after the car has stood on the sun, it is necessary to check up a condition of all fuel system immediately.
  2. Uncover a fuel tank and check up it on presence of damages and corrosion. The sealing lining on a cover should be whole. In case of presence of damages or corrosion replace a cover.
  3. Survey inlet and returnable lines of fuel system on presence 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 not ослабли.

On the cars equipped with system of injection of fuel before to serve fuel hoses, it is necessary to dump pressure in system. Address to the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases.

  1. As some components of fuel system - for example, a fuel tank and some lines of fuel system - are in the bottom part of the car, they are easier for examining, when the car is raised лебёдкой. If it is impossible, поддомкратьте the car and establish it on support.
  2. On the raised car examine a fuel tank and a bulk mouth on presence of holes, cracks and other damages. Special attention give to a connection condition between a bulk mouth and a tank. Sometimes fuel leaks occur owing to easing of collars of fastening of a rubber mouth or because of damage of a material of a mouth. 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, do not try to repair a fuel tank (excepting its replacement rubber a component). The flame of the welding device or any other open fire can easily lead to explosion of evaporations of gasoline in a tank.

  1. Carefully check up all fuel hoses and the metal lines going from a tank on presence of weakened connections, twisting, signs of deterioration of materials of hoses and other damages. If necessary make repair or replace the damaged sections.
