2.) I want to calibrate a fuel dipstick, so I remove a gallon at a
time while taking readings. After I read the tank, I return the
fuel to the tank.

I've been told this is a violation. The person who tells me this
can't cite a FAR, and I can't find one in my own search.

I hope it is not a violation, I've had to do this at remote
mountain
airstrips
for years. I have seen tanks calibrated(Sticks & Gauges) in an
approved shop.

Greater likelihood is that you may be violating an AIRPORT rule. If
your field does not permit self-fueling, then the activity you note
would probably be considered a violation. But FAR's???? Naahh !

Fly it to a remote strip and do as you wish, but follow the antistatic
procedures others have mentioned...
