I'm looking for an accurate fuel measuring tool for pre-flight. Any suggestions on tank dip tools? I have a 7A.
Thanks!
Andy.

I used a hollow plexi glass tube. Ground calibration marks on it. Put in the tank, put your finger over the end and pull the tube out of the tank. Can be read in any lighting conditions and doesn't dry out in hot winds.
The alodined strip is about 5.16" wide, .025 thickness and 1/16" holes drilled for each 1/2 gallon.
Are you meaning 5/16"?
Pretty sure a 5.16" device will not fit through the gas filler hole.
The only downside is that it does soak up a bit of fuel, so it needs to dry out befor I can put it back in the plane.

I don’t get what the need is. The tank floats and fuel totalizer provide independent redundancy. Also I know that right when the fuel is on the verge of not being visible anymore from the fill point, there is 10 gal left. What good is a stick? Nothing to measure using a stick when less than 10 gal and I’m fine with float gauges, totalizer and visual check when it’s more than 10 gal.
or I’m going some place close with cheap fuel..

I have used this one from day one. I alway check it before first flight of the day.

I plotted these and there was a little 'noise' evident, and I also wanted a finer scale on the dip stick so I don't have to interpolate 'by eye'. So I wrote a little Python script to fit a 3rd order polynomial (gallons vs reading) and then evaluated at the integer and half-integer readings.
Does anybody have these measurements for a RV9A?
Thank youMeasuring from the furthest outboard edge of the filler.
4 gallon - .3"
5 - .7"
6 - 1"
7 - 1.3"
8 - 1.6"
9 - 2.0"
10 - 2.4"
12 - 3.1"
14 - 3.9"
16 - 4.9"
17 - 5.4"
18.3 - touches the bottom of the neck
Like many, simple 1/2" flat bar of AL. Marked with die set the measurements above and drilled holes to capture a bit of fuel to make it easier to read. Found that a rough buff with sandpaper lets the fuel bite on the side of the stick as well making it easier to read.
