Helo,
In addition to adding a second bilge pump I have enough room under my rear seat for a second fuel tank. This will give me an additional 19 gallons. How would I wire two tanks up to read off one gauge, if possible. I have a manual fuel valve for switching from tank to tank I used earlier for running a six gallon spare. But I never wired it in. I pretty well versed in electronics and wiring but I can't, for the life of me, figure this out. I'm maxed out with gauges on my dash, so this is why I want to only use one. Any comment or concerns is greatly appreciated.

Thanks,
Tom

SPDT toggle switch with both sender leads coming into it, gauge tied to the common.
