RE: Welcome to Club SAITO !
I also use linkadrip's tank setup on almost every plane. I also use the Hangar 9 fuel dots, since they agree with me (idiot proof) and don't need a special docking connector.
With a length of silicone fuel line directed to the the bottom or in a bottom corner of a rectangular tank, I can draw every drop of fuel out when defueling through my fueling line. I've tried double clunking, but find it to double the chances of having the clunk come loose.
Be careful in choosing silicone to use in the tank. I've had some crystallize and disintegrate in a year's time. What's best to use in the tank?
