PERFORMANCE ORDER
1. To weaken deaerator (And) filter fastening and a bolt (5 – see fig. System of injection of fuel) couplings of the pipeline of supply of fuel to the fuel pump.
2. Under a deaerator and the coupling of the pipeline to substitute capacity.
3. In the engines equipped with the manual fuel pump with a shaped polygonal head to unscrew a head of the manual fuel pump.
4. To press the button of the manual pump until the fuel following from a deaerator, will not contain air vials.
5. To tighten a deaerator of the fuel filter.
6. To press the button of the manual pump until the fuel following from under a bolt of the coupling of the weakened pipeline of supply of fuel to the fuel pump, will not contain vials of air and immediately to tighten a bolt of the coupling of this pipeline.
7. To stop supply of fuel when the button of the pump will start to show strong resistance. In the engines equipped with the manual fuel pump with a shaped head to tighten a hand a head of the fuel pump.
8. In case were replaced (or unscrewed) injection pipelines, it is necessary to weaken nuts of their fastening to nozzles 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 supply of fuel on nozzles and to start the engine.
