Flashforge Adventurer 3 Lite PTFE Tube Replacement Tutorial

How to replace the PTFE tube on your Flashforge Adventurer 3 Lite 3D printer.
Please note: If your Adventurer 3 has a filament runout sensor, don't disconnect the sensor wire, just hold the filament feeder assembly partially removed from the printer with the sensor wire still attached while you change out the PTFE tube.
