Dropping pressure in a power supply system

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. 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. Dumping of pressure in a power supply system has to be carried out before service of any of its components for the purpose of minimization of risk of ignition of fuel and receiving injuries by the performer.
2. For dumping of excessive pressure in the fuel tank uncover a jellied mouth.
3. There are two ways of dumping of pressure in a power supply system: disunite the contact socket of an electrical wiring of the fuel pump, or take the Relay of Disconnection of the Chain, – estimate what of actions it can be made with smaller expenses of forces and time. The socket of an electrical wiring of the pump is directly on assembly of the fuel tank (see the Section Removal and installation of the fuel pump).
4. Start the engine and wait for its spontaneous stop, then turn the ignition key in position of OFF.
5. For a guarantee of completeness of a discharge of system turn the engine several times a starter. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!

6. When undocking nipple connections it is necessary to lay over them paper towels for collecting the spilled fuel.
