Sight gauge innerds
Like the Velocity, I believe the Cozy uses sight gauges in the strake baggage area as a indication of fuel level. What, if anything, is safe to place inside this little tube to make the reading easier (instead of just the fuel itself). My first thought is cork as I know it used to be used as fuel floats in old cars. I would prefer to have it brightly colored. What could be used for color? Of course, I don't want something that will disentigrate over time and find its way into the fuel system. I have not used the Adkins (?) aftermarket gauges. Your thoughts are appreciated. TIA.
All the best,
