On the aboove subject, I must admit that I had no prior experience with
composite airframes and the potential (:-) ) for static charge build-up. So,
being ignorant of the possibilities, I elected to do what might be
considered "overkill".

Each of my tanks are filled with the expanded aluminum foil "Explosafe". All
of the material is run through and through with 20 ga. aluminum wires,
firmly tied together where they cross. They are then connected to each
filler cap via a screw and wire lug, and then clamped to the aluminum fuel
lines. External to each tank, a wire is clamped to the fuel lines and are
connected to system ground - which includes the engine.

When I get ready to fuel my Lancair, I clip the fuel island ground line to
my exhaust pipe, thereby insuring that the interior of all tanks are
grounded through the Explosafe, including the filler cap rings. After 500+
hours I have not had a problem (assuming I might have had one without all
the fuss).

I understand that there has been some rumors that Explosafe can harbor
condensed water in the interstices of the expanded foil, but I have also not
seen any evidence of that, either.
