Bought Coleman Lantern Fuel on the way to the airport. Worked very well with lots of rags to remove the residue left behind when removing the protective plastic layer on the Al sheet.
Tried to locate the fuel tank stiffeners in the plans, but there appears that there are no good instructions.
Also trying to determine the best way to allow for the engine return fuel to return to the fuel tank. Fuel should return to the tank being used. But where to run the line and how long should it be are questions to answer.
