This process is performed as follows:
 Ignition ´ON´ The electronic fuel pump is switched on for 20 seconds to vent the fuel system and
generate the desired fuel pressure. Wait until the electric fuel pump has disconnected from the control
unit.
 Ignition ´OFF´ Repeat this process at least twice until the fuel system has been vented.
