5.2.3.1. Check of a regulator of pressure of fuel

PERFORMANCE ORDER

1. Disconnect and muffle a vacuum hose of a regulator of pressure of fuel. Connect to a regulator the manual vacuum pump. Start the engine and consider the indication of pressure of fuel without depression on a regulator. Create depression in a regulator and again consider pressure of fuel. With depression growth on a regulator pressure of fuel should decrease. Compare indications with specified in subsection 5.2.1. 2. Attach a vacuum hose to a regulator and check up pressure of fuel idling, Compare indications to the standard. 3. Disconnect a hose and again consider pressure, – as soon as the hose is disconnected pressure should increase jump to the top standard limit. If pressure of fuel idling at the disconnected hose too high measure вакууметром depression size on a vacuum hose. If вакууметр shows nothing, check up tightness of a soaking up collector and the levelling chamber. 4. On early models the vacuum valve of a regulator works from the contact gauge of temperature, on later copes the processor block. Check of the vacuum valve is carried out in car-care centre. 5. If pressure of fuel too low press a return hose. If pressure does not increase, the pump is faulty or the fuel highway is littered. If pressure sharply increases, replace a pressure regulator. 6. If pressure of fuel too high execute actions on декомпрессии systems, disconnect a return gasoline pipe line and blow it. If the return gasoline pipe line is not littered, a pressure regulator replace. 7. If the behaviour of pressure differs from described in item 2 replace a pressure regulator. 8. Cautiously remove a manometre. 9. Wrap the union of the distributor of fuel, preliminary having replaced linings. 10. Wipe the spilt gasoline. 11. Start the engine and check up presence of a leak of gasoline.
