I know there have been a bunch of threads on this topic already, but here is another. I do have the older plastic Kitfox header tank, and it has the one fitting up on the side near the top where I could put this. (yes, I know Kitfox has a much better one that is made out of aluminum, but my plastic one doesn't leak,, yet) I already had some red warning lights so I have one to put in the panel. I did order a red warning light with a real loud buzzer that I may use instead. Today this flow level switch showed up in the mail. Anyone using one of these? Or see any reason why it won't work? It's made for fuel contact. JImChuk
