I went out to calibrate my Princeton Capacitance meter today and the first step
is to fill the tank. I Have the metal tube between the filler neck and the tank
with a black rubber coupling on each end, between the metal and the glass filler
neck, and the metal and the glass tank. I found that gas leaked a little
on both ends of the metal tube. When I used a paper towel to clean the gas off,
it had a big, black streak on it from the rubber coupling tube. More gas, more
black. The tube looks like radiator hose, but I am sure it came with the kit.
If avgas is causing it to break down, am I using the proper material on both
ends? If not, what should be used?
