Mark fuel gauge

[DannyDot]

I have generated usable fuel remaining vs. fuel gauge wire height for 3 point stance and flight attitude. While on the ground I can measure the wire height with a ruler. Is there an FAA approved way to mark the fuel gauge wire so I can read usable fuel while in flight. Obviously having something like paint come off and contaminate the fuel would be very bad. I can't think of a way off the top of my head.

Re: Mark fuel gauge

We have a couple notches filed in our fuel gauge wire. One reads half tank and the other I use as "be on the ground before it gets there" but not sure of what its significance is in gallons. It's about an inch or so above bottom.

For what its worth, when I reworked my fuel tank float I used a stainless welding rod to the float. I drained the tank, put in 3 gallons of fuel, and then formed the bend on the rod to just touch cap. Logic being I can estimate fuel from amount of rod drop, but when the rod bend touches I would know I had 40 minutes left, not that I have ever let that happen..

I have used colored (painted) sections of the fuel wire that indicate 1/4, 1/2, 3/4 and empty since 1982. Never had a problem. Dave

What kind of paint did you use?

I never wasted my time, I use the Univair cub cap and when it bottoms out I have 30 minutes of fuel left. Tim
