Yes, please. That would be greatly appreciated.
I bought this one

Fuel Stik For RVAircraft | Aircraft Spruce ®
Fuel Stik For RVAircraft Extremely light, high impact plastic tubing with aluminum rings resist damage.
With the -10, I can stand in front of the wing, open the pilot side door door, turn on the master, and verify the fuel level via the G3X indications without climbing onto the wing. That doesn't replace a visual confirmation of the fuel level, but on a flat surface and with calibrated fuel gauges, I find it to be adequate for estimating/verifying fuel quantity.
I take it you have fuel senders both sides of the tank? I don't and anything over 21 gals is not readable on my calibrated but unreadable G3X fuel level indicators.
BTW I thought interesting the number of negative comments on ACS for their Fuel Stik For RVAircraft that you can't get a reading when the tank is less than 1/3-1/2 full. I guess they don't understand the effect of dihedral.
My gauges read to about 25 gallons. If I need more than that, I'll generally fill the tanks all the way. Between the gauges and the totalizer, I know how much fuel is in the tanks. Removing the fuel caps and eyeballing it is basically a check and balance to validate what the gauges and totalizer indicate.
Appreciate the input, for my 14 the readable tank reading started at 21 gals and since the 10 has the same tank profile figured 21 gals was correct and did not question the number but after thinking about this they both have the same number of bays (6) and the float lives in the first bay of both so if the 14 is 21/25=84% so my 10's tank readable indication should be 84% of 30 gals or 25 gals. I have been questioning my tank data and that is why I wanted the stick to confirm my numbers.
My first job out of college I worked for a petrochemical refining company that produced organic polymers from a large bulk tank farm. The foreman who would hand measure the tanks every month had a great expression "if it's not on the stick it's not in the tank regardless of what your computer inventory shows". He was correct and now trying to find a stick.
I have the Princeton capacitive sensors and I can read only the last 17 gallons in each tank. I calibrated three separate times using 1 gallon increments, so I am pretty sure they are accurate. The totalizer is always within .6 of a gallon at top off; considering that I don’t fill it to the rim every time, the error is likely less than .6 gallons. Close enough. I always check the tanks visually during preflight but it’s more of a “coarse” check, ie is there actually some fuel in the tank? If I can see the fuel, there is at least 15 gallons in the tank.Appreciate the input, for my 14 the readable tank reading started at 21 gals and since the 10 has the same tank profile figured 21 gals was correct and did not question the number but after thinking about this they both have the same number of bays (6) and the float lives in the first bay of both so if the 14 is 21/25=84% so my 10's tank readable indication should be 84% of 30 gals or 25 gals.

I get it 100%. We have multi-hundred thousand pound silos at work. We have load cells, radar level sensors, and the like. The most accurate and repeatable readings come from someone climbing on top of the silos and dropping a plumb bob on the end of a tape measure...My first job out of college I worked for a petrochemical refining company that produced organic polymers from a large bulk tank farm.

Thanks, so starting at the top 0 inches represents the bottom readable fuel amount and looking at the dihedral I come up with there would still be ~7.5 gals in the 30-gal tank? Each yellow mark represents X gals? It would seem to make sense to have this a whole integer, but 4 gals seems low and 5 gals seems high. (assuming my 7.5-gal number is correct)
Thanks !
I bought the generic, unmarked stick tube from Spruce. Started with a completely empty tank, filled to 5 gallons, marked the stick (barely readable, very close to the bottom of the stick). Kept adding 5 gals at a time and marking the stick at each interval until I had it marked at 30 gal/full. My tank floats show full at 25 gallons, so my G3X doesn't accurately measure levels until 25 and below.
