Activating the fuel pump.
A "buzzing" noise is heard from the fuel pump when it is activated.
WARNING:
The fuel pipe shall only be filled when replacing the pipe. If you fill with fuel for too long, there is a risk of smoke development or heater damage. However, it is necessary to fill the pipe when replacing the fuel pipe as the control unit only permits 3 heater start attempts. It shall take a maximum of 8-10 minutes to fill up with fuel when replacing the pipe.
