I'd weld in a pipe coupling, and then screw into that a compressing
tubing connector, with the brass ferrel replaced with a fat oring that
would seal the wire.

I'm working on putting a capitive fuel gauge into my welded aluminum

a 3/16" tube run the wire through it, and pack it full of a ProSeal type
epoxy. I'm wondering, is there a smarter way to accomplish the task?
