About the balls hanging up where the fuel level is not.... They do that because of static electricity, they are made from cork. I have quit putting them in the kits. Leaks... I've had mine for 28 years NO leaks, That's because they are installed properly. The white plastic background is NOT compatible with enthanol laden fuel. I have started sending out aluminium backgrounds now for pilots who insist on using that type of fuel. The plans called for a glass to glass layup for a fuel window. And it will work fine if your epoxy does not darken with age. The ultra violet causes it to turn dark and you will not be able to see any kind of fuel levels very well, especially in low light conditions. I use an STC'd fuel computer (Shadin) to keep track of my fuel remaining and do some long legged flights (LAX to DFW) which takes most all of the fuel available. vance atkinson
