If there is air in the fuel system, this can cause damage to the injection pump.

The manual bleed pump HFP was developed to bleed the fuel system after a filter change or repairs to the fuel system. It is used in the fuel circuit to bleed the fuel filter or the complete fuel circuit.

The bleed pump is installed in the direction of flow after the fuel filter. It is suitable for diesel, biodiesel and heating oil.
