I used a couple of float senders, wired thru a 2 pole switch to a single level gauge, one pole for each tank sender. The switch is a momentary on type. The float senders are plastic with a float that slides up and down the housing. I wish I could remember where I got them. The gauge is just a 2in water level guage.
