1/4" hole in the tank top near an access hole should you ever have to get
into the tank to work on it.

Rubber or vinyl grommet into the hole.

#4 or #6 machine screw, large area flatwasher top and bottom, solder lug top
and bottom, locking nut on the bottom. Screw, solder lug, flatwasher,
through the grommet, flatwasher, solder lug, nut.

Solder capacitor wire to lug inside of tank and solder wire to rest of
circuit from top solder lug.

I'm working on putting a capitive fuel gauge into my welded aluminum tank.
In consideration of how to bring the wire from one of the plates out of
the tank...the best I've been able to come up with is to weld in 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?
