GENERAL INFORMATION

Prevention

During the work on fuel system it is necessary to take off previously pressure in system.


FUEL HIGHWAY AND NOZZLES

Removal

PERFORMANCE ORDER
1. Disconnect the negative plug of the accumulator.
2. Remove a vacuum pipe from the fuel regulator of pressure (it is specified by an arrow).
3. Remove hoses of supply of fuel and returnable hoses from the fuel highway.
4. Switch-off electric sockets and hoses from a forward part of the fuel highway.
5. Remove electric sockets from fuel nozzles.
6. Unscrew fastening bolts (are specified by shooters) the fuel highway and remove it from an inlet collector. Remove consolidation from each nozzle.
7. Take nozzles from the fuel highway and remove the top sealing rings of round section which have to be replaced with new.

Installation

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal.
2. Consider the next moments:
     – establish new sealing rings of round section on nozzles;
     – for simplification of installation oil engine ring consolidations and establish nozzles and the fuel highway into place so that any of ring consolidations was not displaced;
     – start the engine and check tightness of fuel system.

FUEL PRESSURE REGULATOR

Removal

PERFORMANCE ORDER
1. Disconnect the negative plug of the accumulator.
2. Disconnect a vacuum tube from the regulator.
3. Having enclosed pure rags under the regulator weaken a collar and take the fuel regulator from the highway.

Installation
