This procedure must be carried out in the following cases:
- disconnecting the fuel line;
- air lock in the fuel pump fuel circuit;
- engine shutdown when there is no fuel in the fuel tank;
- replacing the fuel filter.
Caution! When removing air from the fuel system, it is necessary to apply voltage to the electromagnetic engine stop valve to open the valve.
Fastening the return fuel line
1. Check the presence of fuel in the fuel tank.
2. Place a suitable container under the fuel filter to collect any spilled fuel.
3. Unscrew the air bleed screw (1) on the hollow bolt of the fuel filter outlet hose and unscrew the handle of the booster pump (2).
4. Pump until fuel comes out of the air bleed screw without any air bubbles.
5. Press the pump handle and in this position tighten the air bleed screw.
6. Unscrew the air bleed bolt (indicated by the arrow) located on the side of the high-pressure fuel pump, or the return fuel line mount and pump until fuel comes out through them without air bubbles.
7. Stop the fuel supply when the pump button begins to offer strong resistance. On engines equipped with a manual fuel pump with a shaped polygonal head, tighten the fuel pump head by hand.
8. If the injection pipes were replaced (or unscrewed), you should loosen the nuts that secure them to the injectors, press the accelerator pedal all the way down and turn on the starter until fuel starts to flow out from under the pipes with the loosened fastening.
9. Screw the fuel supply lines to the injectors and start the engine.
10. Check the tightness of all fuel line connections.
