How do I stop this?

I finished reinstall.

Thanks.

where do I get the tool to crimp on the ferrules.

Thanks Bill. This info is very helpful.

As As I used almost all of the PTFE tubing and brass fittings from my installation kit; where would I get the new brass fittings to hold the PTFE tube into the 3d Chameleon extruder? Would you be willing to send and or sell me the extra parts at a reasonable price that I would need to redo my installation correctly?
