THE GENERAL DATA

Regulator of pressure of fuel

 The regulator is informed with a cavity of a soaking up collector through a vacuum hose.

Bolts of fastening of a regulator of pressure of fuel (system L-Jetronic)

 1. A suppressor of pulsations

2. Fastening bolts

3. A vacuum hose

Bolts of fastening of a regulator of pressure of fuel (system Motronic)

 A.Bolty of fastening

V.Obratnyj a gasoline pipe line

S.Shlang of a regulator

Check

PERFORMANCE ORDER
1. Execute декомпрессию.
2. Disconnect the battery from weight.
3. Disconnect from a regulator a fuel hose and on its place establish a manometre.
4. Attach the battery, connect the pump, include ignition and check up presence подтеканий fuel.
5. Attach the vacuum pump to the place of a vacuum hose, include the fuel pump. Consider pressure of fuel at depression creation on a regulator and without depression. Pressure of fuel should decrease in process of depression increase.
6. Attach a vacuum hose, start the engine and consider pressure of fuel idling. Disconnect a vacuum hose, – thus pressure should increase sharply.
7. If pressure low press a return gasoline pipe line. If thus pressure does not increase, the fuel pump is faulty or the direct gasoline pipe line is littered. If pressure sharply increases, replace a pressure regulator.
8. If pressure too high stop the engine, disconnect and blow a return gasoline pipe line. If the return gasoline pipe line is not littered, replace a pressure regulator.
9. If pressure change does not correspond described check up depression on a regulator, having attached to the place of a vacuum hose вакууметр (the engine should idle).
10. If depression is, a pressure regulator replace. Otherwise believe tightness of a hose and the union on vacuum connection.

Replacement

PERFORMANCE ORDER
1. Execute декомпрессию and disconnect the battery from weight.
2. Disconnect from a regulator return fuel and vacuum hoses. Turn away bolts of fastening (arrow) and remove a regulator.
3. Installation is carried out upside-down. Replace a ring lining.
