Round Command Link Fuel Gauge - Which Tank?

[fseiersen]

I have twin 150's with the round Command Link gauges. Both tanks are wired to to the Speed Fuel gauge. How do I know which tank is being displayed by the gauge?

I've read all the manuals and can't seem to find any reference. They provide connections for two tanks so there should be someway to select one or the other.

Thanks

The Command Link round speed/fuel gauge will only connect and display one fuel tank level(the square Command Link will display two tanks), the tank sender that is connected to the pink wire from speedometer is the only tank that display(same speedo wire harness is used on square and round gauges).
You would have to install a toggle switch and connect the the tank senders to toggle and connect speedo pink wire to common terminal on toggle in order to switch to tank you want level displayed on gauge.

Thanks for the info. That's what I was thinking the solution would be. The confusing thing was that there were 2 inputs on the speedo.

Thanks again
