The prevention

At removal of air from fuel system it is necessary to submit on the electromagnetic valve of a stop of the engine pressure for valve opening.

---

Fastening of the return топливопровода

PERFORMANCE ORDER

1. To check up fuel presence in a fuel tank. 2. To establish under the fuel filter the corresponding container for gathering of the poured out fuel. 3. To unscrew the screw of removal of air (1) on a hollow bolt of a target hose of the fuel filter and to unscrew the handle of the pumping up pump (2). 4. To make pumping by the pump until through the screw of removal of air there will be no fuel without air vials. 5. To press the handle of the pump and in this position to screw up the screw of removal of air. 6. To unscrew a bolt of removal of air (it is specified by an arrow), located sideways on the fuel pump of a high pressure, or fastening of the return топливопровода and to make pumping by the pump until through them will not leave fuel without air vials. 7. To stop fuel giving when the pump button will start to show strong resistance. In the engines equipped with the manual fuel pump with a shaped polygonal head to tighten a hand a head of the fuel pump. 8. If were replaced (or unscrewed), injection pipelines, it is necessary to weaken nuts of their fastening to atomizers to press an accelerator pedal against the stop and to include a starter while from under pipelines with the weakened fastening fuel will not start to pour out. 9. To screw pipelines of giving of fuel on atomizers and to start the engine. 10. To check up tightness of all connections of fuel pipelines.

THE FUEL FILTER

Filter replacement

Knot of the fuel filter

1 – the holder of the filter, 2 – a replaced element of the filter, 3 – a sediment bowl, 4 – the manual fuel pump

The replaced element of the filter is clamped between the holder of the filter and its sediment bowl.

Replacement of an element of the fuel filter

With – a sediment bowl, Е – a drain bolt

PERFORMANCE ORDER

1. To unscrew a bolt of fastening of a sediment bowl to the holder of the filter. 2. To disconnect a sediment bowl and a replaced element of the fuel filter. 3. To establish a new replaced element on a sediment bowl and to move up to держателяю the filter. 4. Cautiously to screw up a bolt of fastening of a sediment bowl to the holder of the filter. 5. To check up tightness of connections of the fuel filter.

Removal of water from a sediment bowl

PERFORMANCE ORDER

1. To substitute under the fuel filter capacity, to weaken a drain bolt and a bolt of fastening of the pipeline of tap of fuel from the filter. 2. To tighten both bolts after water will cease to follow.
