"Any better ideas for indicating fuel level besides what appears to be just white paint with a fine brush?" Well, Greg, a long time ago in a far off land, I ran the fuel levels in all four tanks down to negligible. Then a crew of guys an I refilled the tanks in ten gallon increments while I marked the tanks behind the sight tubes. After the levels reached the top of the sight gauges (several inches below the tank tops) we continued filling clear up to the tanks' tops, keeping track of the amount of fuel added after the level went out of sight in the tubes. With a known tank capacity in hand, I was then able to convert each 10-gallon mark into actual remaining gallons in each tank. I then got some stick-on numbers and applied them to the tanks. Been there twenty-plus years. Rich Gano CALYPSO (GB-42 #295) Southport, FL (near Panama City)
