I don't know of anything that
prohibits a private owner from defueling his part 91 aircraft and
refueling it with the properly stored "used" fuel. Common sense
requires the fuel to be kept free of contamination and proper safety
measures utilized in the refueling process.

From the things I have seen, there is even more danger in defueling.
There can be considerable static electricity generated in fuel falling
into a fuel container.

Google for "Kelvin water dropper experiment".

I think the key is to make sure that the airplane and the container are in
good electrical contact with each other. Just like you see the line guys
do every time they fuel your plane from the truck.
