Creating a Grumman-specific fuel tank dip stick

I use a "Fuelhawk C-152" from J-Air, available at any FBO. It doesn't matter whether you use this, a paint stick, or your favorite pen, as long as the length of it is sufficient so you don't drop it inot the tank (that would suck). What counts is the height of the fuel from the bottom of the tank, immediately below the cap opening. Sporty's makes a "Universal Fuel Gauge", P/N 5304A. I used a permanent marker for the marks, and it's lasted a few year's worth of fuel dips so far.

The first number is the gallons useable remaining, the second is the distance from the bottom of the stick (tank). Experience with many fillups has shown this to be a very handy *GUIDELINE*; I'd entertain any others' experiences to adjust this.

Gallons - Distance

7 - Bottom of tank (0") 8 - 1/4" 9 - 7/16" 10 - 11/16" 11 - 13/16" 12 - 1" 13 - 1-1/4" 14 - 1-1/2" 15 - 1-13/16" 16 - 2-1/16" 17 - 2-3/8" 18 - 2-5/8" 19 - 3" 20 - 3-1/4" 21 - 3-5/8" 22 - 4-1/16" 23 - 4-1/2" 24 - 4-15/16" 25 - 5-1/2"
