7.21. Regulator of pressure of fuel

Removal

THE SOHC MODELS (EXCEPT MULTEC)

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. For improvement of access to a regulator of pressure of fuel remove a regulator of turns of idling. Disconnect a casing from fuel nozzles and move it aside, thus do not stretch a wire. Compress brackets of fastening and, having pulled a casing of wires on itself, remove it from fuel nozzles.
3. Arrange pure rags under a regulator of pressure of fuel to collect fuel which can flow out at regulator removal.
4. Weaken collars and remove fuel hoses from a regulator of pressure of fuel.
5. Remove a vacuum pipe from the top part of a regulator of pressure and remove a regulator.

THE SOHC MODELS (WITH SITEMA MULTEC)

Arrangement of a cover of a regulator of pressure of fuel

And – directing pins;

In – screws of fastening of a cover


PERFORMANCE ORDER
1. Remove pressure in fuel system.
2. Remove the air chamber.
3. Remove a weight wire from the accumulator.
4. Note an arrangement of directing pins of a cover of a regulator, then, being careful, unscrew screws of a cover of a regulator of pressure of fuel. Pay attention, that at removal of a cover the spring did not jump out. Remove a cup of a spring of a cover, a spring and a diaphragm. Thus mark out them arrange scientific research institute (see fig. Arrangement of a cover of a regulator of pressure of fuel).
5. Replacement of a diaphragm is necessary for making at each removal of a cover.

DOHC MODELS

Arrangement of a regulator of pressure of fuel on the DOHC models

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Disconnect the electric socket from a measuring instrument of a stream of air. Remove a sealing ring.
3. Weaken a collar, a fixing air branch pipe by the right end of a measuring instrument of a stream of air.
4. Using a face key, unscrew four bolts, fixing the air chamber to the throttle case. Raise the air chamber from the case of a throttle and disconnect a hose from the basis of the air chamber, then remove knot air a chamber/measuring instrument of a stream of air.
5. Disconnect two hoses of ventilation of a case from a back part of a cover of a head of the block of cylinders and move them aside.
6. Disconnect the electric socket from the sensor of provision of a butterfly valve.
7. Disconnect a vacuum tube from a regulator of pressure of fuel (see fig. An arrangement of a regulator of pressure of fuel on the DOHC models).
8. Arrange pure rags under a regulator of pressure of fuel to absorb the spilled fuel after regulator removal.
9. Unscrew four bolts located under a regulator and remove a regulator of pressure of fuel.

Installation

PERFORMANCE ORDER
1. Installation of a regulator of pressure of fuel is made in sequence, return to removal. Check correctness of connection of tubes, hoses and electric sockets. Keep in mind that the vacuum tube of a regulator should settle down from above a hose of ventilation of a case on a cover of a head of the block of cylinders.
2. On models with system of injection of Multec fuel execute also following actions:

— establish a new diaphragm so that it correctly settled down in a flute of the case of a throttle;
— correctly arrange a spring and a spring support on a cover of a regulator and a diaphragm;
— establish a regulator cover on directing pins and screw screws;
— tighten screws of fastening of a cover of a regulator of pressure of fuel the demanded moment.

3. In summary before start of the engine check, that there were no leakages of fuel on a regulator for what create pressure in fuel system, switching on and off ignition.
