J-Air Fuel Gauge

[KennyFlys]

Might anyone possibly have used the J-Air Universal Fuel Gauge?

Better yet, has anyone used one in a Cutlass 172RG with 33 gallon tanks?

I'm trying to get a feel for this rascal without having to talk a fuel truck driver into a fifteen minute fill to figure it out.

I bought one to use with my 172RG 33 gallon tanks, I did the 15 minute fueling and came up with the following approximate readings to fuel in the tank.

3 = 11 gallons
5 = 16 gallons
7 = 21 gallons
9 = 26 gallons
12 = 31 gallons

FWIW

Thank you, that's a start. I can plot a few other midway points from there.
