6.7. Removal and installation of the regulator of pressure of fuel

Remember that gasoline is extremely flammable liquid! During the work with components of a power supply system observe all taken measures of fire safety. Do not smoke! Do not approach the venue of works with naked flame or the carrying unprotected by the lamp shade! You do not make service of system in the rooms equipped with the heating devices using natural gas and equipped with a control torch (such as vodogre and dryers for clothes). Do not forget that gasoline is among cancerogenic substances, i.e., - the substances promoting development of cancer! Try not to allow hits of fuel on open parts of the body, use rubber protective gloves, at casual unforeseen contact with fuel carefully wash out hands warm water with soap. Immediately collect the spilled fuel and do not put the rags impregnated with fuel and lubricants near sources of naked flame. Remember that the power supply system of the models equipped with injection of fuel constantly is under pressure. Before starting a detachment of fuel lines, dump residual pressure in system. At service of components of a power supply system put on goggles. Constantly hold near at hand the class B fire extinguisher!



1. Dump pressure in a power supply system (see the Section Dropping Pressure in a power supply system).

2. Disconnect a vacuum hose and the line of return of fuel from pressure regulator.

3. Turn out fixing bolts / release a lock ring and remove assembly of the regulator from the fuel highway.



1. Replace a sealing ring of the regulator of pressure (before installation of a new ring slightly oil it liquid lubricating).

2. Put the regulator of pressure upon assembly of the fuel highway and check freedom of its rotation. At identification of signs of jamming remove the regulator and check whether the sealing ring is overwound.
3. Having installed the regulator properly, achieve combination of bolted openings, screw fixing bolts and tighten them with the required effort (11 H • м). At the corresponding complete set fix the regulator by means of a lock ring.
4. Connect the returnable line and a vacuum hose to the regulator.
5. Connect a negative wire to the battery. Lift pressure in system and check a path for existence of signs of development of leaks.
