My 360 is getting ready for some repairs that includes fixing defective fuel gauges and recalibrating my totalizer. While I’m at it, I’d like to add a switching device that would read the header tank level and automatically activate the fuel transfer pumps when the header tank level drops below, say, 4 gallons and then shuts it off at a header tank reading of about 9 gallons. I saw a 2 ¼” display for such a unit on a friend’s Lancair, but he couldn’t recall where he got if from and doubted they were still available. Does anyone know if they are or what other options might be available? Thanks for any thoughts on this.
