I prefer to ground my system through the fuel drains which I ground via
wire to the main grounding point to prevent that. Static electricity in
a tube like that or during fueling where the fuel filling source and
aircraft are not grounded is dangerous.
Anyway, I think your point has merit.

I see you used plastic tube for the breather. Makes me nervous
remembering Harald Linke's refueling fire. I always use 3/8 versatube
and ground it.
Fuel vapour and droplets running up an insulated tube might act like a
Van der Graff generator and cause a spark. My guess anyway.

Procedure I use at Custom Flight:
1. Open the hole in the fuselage top to allow the boss from the
filler tube to pass through.
2. Align the fuel filler tube to the fuselage side and temporarily
set it against the side of the aircraft, mark where the fuel tube will
set and check that the rubber fuel hose will fit and not be folded or
bent.
3. Cut a piece of scrap blue foam about 1/4 inch thick, and wider
than the fuel tube by about an inch. Set the length from 1 inch minimum
below the fuel filler top hole, and stop near the bottom of the flat
part of the PTFE filler tube.
4. Affix the blue foam to the fuselage side with 5 minute floxed
epoxy on the top and bottom edge and floxed Aeropoxy for the center.
Clamp as necessary. Allow to cure.
5. When secure, chamfer the sides to a 45 and round the edges.
Spread entirely with micro slurry and two layers of glass, and peel ply.
6. Refit the tube, mark the top for the filler cap flush with the
outer fuselage and cut and install the filler cap. Check fit. Once fit
is acceptable, Redux the top area around the filler cap inside and out,
and affix with glass straps as described in the manual. Peel ply as you
will be working around here later.
7. Once all is secure, attach the trimmed rubber fuel elbow and
clamp.
8. Use Pro Seal on just the top and bottom points of the rubber fuel
elbow if you are concerned about fuel leakage in the event of an
overfill. Keep in mind, the fuel tube will have to be cut off to remove
it if using Pro Seal (available at A/C Spruce.).
9. Attach fuel vent tubing as appropriate.

Subject: Fuselage skin distortion at fuel fill
I find only inconclusive information on the forum about fuselage
skin distortion that can develop around the fuel fill tube. I can not
find additional information. Would you steer me to the correct solution
or give me any revised procedure.
Thanks,
Bill McClellan
