The fuel system includes: fuel tank, fuel lines, high-pressure fuel pump (HPFP) with injectors and fuel filter. The current fuel supply is shown on the fuel gauge. The fuel tank is equipped with a ventilation system. If the fuel tank is empty, air should be removed from the fuel system.
Attention! To check if fuel is supplied to the injection valves when the starter is difficult, loosen the union nuts on two valves and start the engine without preheating until fuel appears on the union nuts. Tighten the union nuts and start the engine according to the instructions.
1. If the fuel does not flow, the air should be removed from the system as follows.
2. Fill the injection pump with diesel fuel.
3. Fill the fuel filter with fuel.
4. Tow the car.
5. These measures ensure rapid removal of air from the system.
