Procedure of dump of pressure of fuel

Gasoline is an inflammable liquid in the higher measure, therefore at work with power supply system components it is necessary to observe special safety measures. Do not come nearer AT ALL to a place of work with the lighted cigarette, open fire or the redurable not protected by a lamp shade. It is not necessary to make power supply system service in the premises equipped with heating devices, working on natural gas and equipped with a control torch (водогреи, dryers, etc.) . Each time when arises threat of hit of gasoline on open sites of a skin of hands, put on латексные gloves. Casually got splashes immediately wash off water with soap. The spilt fuel immediately clean by means of rags. The rags soiled by fuel put in 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 necessarily dump pressure in system. Constantly hold near at hand the chemical fire extinguisher of dry type (class).


    Disconnect a negative wire from the battery. Uncover mouths of a gulf of fuel, having dumped thereby superfluous pressure in a fuel tank. Uncover the union of check of pressure of the fuel located on a fuel highway.
    By means of a small screw-driver or a small beard wring out Schrder's valve in the verifying union of the fuel pump. Be ready to gathering by rags выпрыскиваемого thus fuel (wrap up it a sting of a screw-driver and a valve head).
    Wrap up the verifying valve rags (also enclose rags and under it) is is necessary for prevention разбрызгивания fuel at opening of the valve for pressure dump in system. By means of a small screw-driver or a small beard wring out a valve head in the verifying union for dump through it of superfluous pressure (see an illustration above). The spilt fuel immediately collect the rags prepared in advance. Establish a cover on the verifying union of pressure of fuel.
