You will need to 3d print a new mount for the 3dp module, there are quite a few designs on Thingiverse. There's what looks like a silver disk on top of the module with 2 super tiny screws. You'll remove that part and replace it with the 3d printed part. Then you'll need to buy the Pneumatic Fittings (the brass and blue part) as well as a bowden tube for it. The fitting will screw into the part you printed out.
Do you have a blue piece where the filament comes in, where can I buy it?

Is a fuse change possible? Is the process similar?
Fuse? There's no fuse in the extruder that I'm aware of.
