USS 8-64 Drain Tube question

[bannind]

So I have removed and cleaned up my USS 8-64,  I am now looking forward to re-installing the liner with insulation.  The issue I am trying to wrap my noggin around is the installation of the drain tube.  I am almost positive it will have to be removed for re-install (right/wrong)

Do I just put it back in once the liner is in place and silicon around the edge for seal?

You can use a 2 part epoxy, or solder it back in from the top. Make sure before re-installing the tube is cleaned out real good to prevent it from clogging in the future.
