2.6.20. Check of amount of the fuel given by the fuel pump (cars from the 4th the cylinder engine with a free admission)

Check conditions
The minimum voltage of the accumulator is 12,5 Century.
The fuel filter has to be serviceable.
The fuel tank has to be filled not less than on 1/4.
Be convinced of that, the regulator of pressure of supply of fuel is serviceable.
Ignition is switched off.

Procedure for test
Open a cover of the block of safety locks on the left side of the dashboard.
Take out a safety lock from a block of safety locks (the left row, the 5th big safety lock from above).
Connect remote control by means of an adaptor cable to the right plug of a socle.
Connect the tightening plug to the plug (+) joint stock bank of the car.
Turn off a cover of a jellied mouth of the fuel tank.

Fig. 2.54. Engine casing


Remove a casing of the engine (fig. 2.54).

ATTENTION
The fuel system is under pressure. Before opening of system wrap up pure rags a junction. Then, slowly turning off a junction, pit pressure.


Fig. 2.273. Hose of the return fuel-supply line


Disconnect a hose of the return fuel-supply line of poses. 1 from the place of its connection to the distributor of fuel (fig. 2.273).
Put on an auxiliary hose the distributor of fuel and lower other end in a measured vessel.

Fig. 2.274. Discharge of fuel in a measured vessel


Press the switch of remote control and hold it pressed during 15 with (fig. 2.274).

Fig. 2.275. The chart of the minimum volume of the fuel given by fuel knot


Compare the received fuel volume to the minimum volume on the chart (cm3/15 c) (fig. 2.275).

NOTE
Tension on the fuel pump at the idle engine and the working pump approximately on 2 in lower than tension of joint stock bank.

Assembly is carried out in the return sequence.

NOTE
For fastening of all connections of hoses use collars of the corresponding series.

Establish the return fuel-supply line.
