Rod,
Thanks for the kind words.
The blue tubing is Aerotrend Easy Flex tubing. I don't know if it is still available. I got a roll 15 years ago from the local hobby shop and I just ran out. If you find some let me know. I need some more.
The left valve is fuel master. The right valve is smoke oil shut off. The center valve is fuel fill shut off to keep air from entering air trap tank after disconnecting the fuel fill line. The blue line with fuel dot is smoke oil fill. The GSU terminal is on the bottom in the photo.
Thanks
Gary
