Don't be too confident.  I had mine stolen using the quick (sump) drains.
Took a
while, but they got it done.

I have the ultimate answer to people stealing fuel.  I have no header tank
and I fitted the extended wing tanks to compenste for the fuel that would
have been in the header tank.  So I have two little 5 gallon out board
tanks.  Once the fuel from this has been used or stolen there is no fuel to
be seen or that can be stolen.  There is still at least 15 gallons each side
in the inboard part of the tanks which is inaccessible to thieves.
Unfortunately you cannot dip it either.
