To release the tubing from the heatsink simply press down on the black or grey collet in the top of heatsink while pulling on the tubing.
In 1.75mm Direct configurations thought should be given to running the PTFE right up as close to the hobbed bolt/drive gear as possible as this provides the easiest loading and the best performance with all filament types.
If you do not wish to run PTFE up to the hobbed bolt or drive gear you can simply cut the tubing off flush with the top of the hotend.
The photo shows a cutaway of how an optimal PTFE configuration might look in a Wade's-type extruder. The PTFE tubing extends right up to the hobbed bolt.
