First, you need to remove as much of the impacted residue as possible. Second, carefully apply heat with a heat gun, or hair dryer 7 mm (0.25 in) from the dimples on the inlet pipe. DO NOT overheat the pipe. And lastly, while applying heat, grip the expansion tube. Use a turning motion along with a push-pull motion to loosen the impacted expansion tube and remove it.
