I saw too that it (LSK) was no longer in production. Wow...I was getting amped up about the prospect of having a Fuel Gauge, searching for a compatible display, mount, etc. All that only to discover that it's not available. I still haven't given up on the idea, that Sensor could possibly exist under a different description other than fuel Gauge. I also saw the Ultrasonic you're talking about but didn't have a chance to get a good look.i looked for the LSK set up for Hydrostatic fuel gauge and it said it was out of production. However found an ultrasonic sender that sticks to bottom outside of tank but wonder how much of it would be seen...the brain box would definitely fit up to bottom of back bone, then was thinking of milling the top of air filter cover to put in a LED strip light. 4 green 3 amber 2 red Last red would pulse. with that wouldn't have to worry about where to mount gauge.
