Fuel gauge ideas

The wire doesn't help nor hurt the ability to see the fuel level. The stripes on the placard help a lot due to the diffraction of the fuel in the tube. The stripes appear vertical through the fuel.

I have the sight tubes on my Series V. They were installed 8 years ago and have worked fine. One caution though. When they start to discolor, check them especially carefully to see if they've also hardened. My aircraft is hangared and I thought the discoloration was normal, but during the annual condition inspection, when I touched them, they were hard and actually cracked and crumbled. My recommendation: replace them at the first sign of discoloration and save yourself a leak issue (replacement is easy and inexpensive.)

I replace mine every year. It doesn't take long and all tubing like that seems to degrade quickly when it sees auto gas, ethanol free or not.

Mine has never met gasoline and they are already discoloring.
Guess I’ll be replacing it before adding fuel.
