Bill,
It is clear from your response below that you are definitely an experienced builder!

Greyhawk,
Having to drink the wine to obtain the corks is the major advantage of those old float switches (white). I also had to glue the corks to the floats on our 320 (also still working well). Unfortunately, the newer (black) float switches that Spruce sells now will rise to the occasion in avgas so there is no longer any reason to drink wine... unless you’ve had a particularly good airplane building day... maybe a particularly bad building day, or perhaps...high tide?... a day of the week ending in “day”?

Bill, Rob, et al,
Yes Bill, even if one used the float switch supplied by Lancair (circa 1989) that, since the float was not sympatico with the specific gravity of fuel, required cutting into the float, adding two wine corks and coating them with epoxy. I think I did it right because it still works, but I don't remember much after having to drink two bottles of Santa Margarita Pinot Grigio in order to get those corks. It could have been worse - luckily the corks used by Chivas Regal were way too short.

Rob,
The optical switches work great with the Pillar Point low fuel warning system. For the automatic fuel transfer system the float switches work best.

Further to my recent post about float switches to use in the header tank of a LN2 aircraft, Silvio kindly posted the response, below, on the List. These sensors appear to be very small, light and easy to install in the header tank. I was wondering whether anyone else on the List has used them, and if so, what your experience of them has been – good or bad.
Thanks again in anticipation.

There is an optical switch that works very well in my Lancair. You will need some electronics. Do not have PN but you can look at Google. See attached sheet.
