Damaged peek insulator pipe

Buy an E3D or other all metal hot end and be done with all the problems that go along with standard hot ends.

My extruder jamed pretty bad during a print, and I am noticed that the white plastic guide inside the peek insulator pipe had popped out a little. basically the guide the filament first goes trough. have anybody experienced this before? how do I fix it? at this point the peek barrel jams constantly because the white guide is loose and jumps up out of the barrel creating a cap that fills with abs.

Also, solidoodle dose not sell a new peek barrel for the solidoodle 4(new extruder)

It looks like Solidoodle is no longer using the standard groove mount? Yikes.
