An FAA ops inspector at HQ once gave me a list of all of the regulatory
agencies pilots have to answer to. One of them was the EPA. If there is any
prohibition against doing what you suggest you will find it in EPA regs, not
FARs. The FARs are only the tip of the iceberg.

Does anyone know of a FAR that prohibits removing fuel, avgas in this
case, and then putting it back into the same plane? The plane is flown
for part 91 service only.

Examples:

1.) The plane is 50 pounds overweight for conditions. 10 gallons is
siphoned out into a clean, single-purpose, approved for gasoline
container. The sealed container is stored in a safe place. 2-3 hours
later, upon completing the trip and returning to the field, I pour it back
into the tank.

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.
