Roger, I tried the blue tubing in my KR and it discolors very fast. Also with the tube being blue and the avgas being blue it was just to difficult to safely see the level of fuel in the tank. I changed mine out to clear because even when the clear begins to discolor, you can still see the level of fuel in the tank.

I used the blue tubing made for gas in Aircraft Spruce?s catalog. I made a back ground plate for the sight tube out of a strip of aluminum with a piece of paper glued to it with 1/4 inch black stripes spaced 1/4 inch apart that are at an angle. This is attached to the tube with small wire ties. The diffraction of light through the tube will change the apparent angle of the stripes between the part of the tube with gas and the empty part. It works well with water, but I haven?t tried it with gas at this time. I will probably will fill the tank this weekend and start the engine for the first time. I will update later. Hoping to make the Gathering in 2013 in my new KR2! Roger Bulla rbu...@cdmsinc.net _______________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
