Removing Air from Fuel Lines

Model: Volkswagen Passat B6, 3C - Years 2005-2010
Part: Fuel pump

This video illustrates how to eliminate any air that may have formed in the fuel line of your car. If air has entered the fuel line, perhaps when changing the pump filters, there is a very simple way to remove it. First, connect the examiner to the car and check that the pumps are functioning; then, access the connection of the pump located behind the rear seats and use a 12V bridge to power the pump to purge any air present. Finally, repeat the operation on the pump located in the engine compartment and test everything.
