Disconnect electric shtekerny connection on a deaf flange (fig. 2.242)
Connect remote control with an adaptor cable by means of an auxiliary wire from a set of supportive measuring applications to contact 1.
Stick the 2nd contact of the plug of an adaptor cable with an insulating tape for prevention of short circuit.
Connect contact 4 by means of an auxiliary wire from a set of supportive applications of measurement to the mass of a body.
Connect the tokosjemny plug to joint stock bank of the car (on plus).
Turn off a cover of a jellied mouth of the fuel tank.
Disconnect the giving fuel-supply line.
Connect the device of measurement of pressure with adapters to the giving fuel-supply line.
|Fig. 2.243. Installation of the device of measurement of pressure with adapters
Put on an auxiliary hose the device of measurement of pressure and lower the second end in a reception vessel (fig. 2.243)
Open the locking crane of the device of measurement of pressure. The lever shows the direction of course.
Ventilate fuel system, for this purpose shortly press the button on the remote control.
Close the locking crane of the device of measurement of pressure. The lever is installed across the direction of course now.
Press and do not release the switch of remote control until pressure on the device of measurement of pressure does not cease to grow.
Preset value: прибл. 6 bars (5–7 bars) of excessive pressure.
If the preset value of pressure is not reached, check giving of the electric fuel pump.
