You know, I did search for epoxy injection, and all I got was for injecting into concrete, which is at a somewhat different scale. But syringe opens up other possibilities. While most syringe applicators look to be two-nozzle, and bigger than the space available here, I found a syringe for the syringes (http://www.jamestowndistributors.com...ct.do?pid=2096). How big the tip is, I don't know.

This would invalidate the warranty, I suppose. Also, it was indicated earlier in the thread that a ckt board sits right above the port. Was that the fix that was applied after pre-production experience; and wouldn't that board get stuck if exoxy is injected?
