Example of Pressure/Volume Loss in Pump

Pressure/Volume Loss in High Pressure Pump
When the required target pressure/volume cannot be delivered due to fuel supply line or pump damage
Ex.:
• Air in fuel supply line
• Excessive vacuum pressure in fuel supply line (-300 mbar)
• Burnt out or mechanically damaged pump
• Supply fuel with increased temperature ( > 65°C)
