Procedure of dumping of pressure of fuel

Gasoline is in the highest measure flammable liquid therefore during the work with components of a power supply system it is necessary to observe special precautionary measures. Do not approach the venue of works with the lit cigarette, naked flame or the carrying unprotected by the lamp shade AT ALL. It is not necessary to make service of a power supply system in the rooms equipped with the heating devices using natural gas and equipped with a control torch (vodogre, dryers, etc.). Every time when arises threat of hit of gasoline on open sites of skin of hands, put on latex gloves. Immediately wash away incidentally got splashes water with soap. Immediately remove the spilled fuel by means of rags. Put the rags soiled by fuel to such place where there is no probability of its casual ignition. The power supply system constantly is under pressure therefore before starting a detachment of any of fuel lines surely dump pressure in system. Constantly you hold near at hand the chemical fire extinguisher of dry type (class B).


  1. Disconnect a negative wire from the battery. Uncover a mouth of the gulf of fuel, having dumped thereby excessive pressure in the fuel tank.
  2. Uncover the union of check of pressure of the fuel located on the fuel highway.
  1. By means of the small screw-driver or a small beard wring out Schröder's valve in the test union of the fuel pump. Be ready to collecting by rags of vypryskivayemy at the same time fuel (wrap up it a sting of the screw-driver and a head of the valve).
  1. Wrap up the test valve rags (also enclose rags and under it) - it is necessary for prevention of spraying of fuel when opening the valve for dumping of pressure in system.
  2. By means of the small screw-driver or a small beard wring out a valve head in the test union for dumping through it excessive pressure (see an illustration above). Immediately collect the spilled fuel by the rags prepared in advance.
  3. Install a cover on the test union of pressure of fuel.
