Upgrading a flying RV6A panel to G3X....anybody know if it?s possible to leave the existing Vans fuel gauges in place and use them in conjunction with the G3X digital gauges?

Thanks -Steve
 
Yup - they hooked up fine on two planes I’ve got with G3X.

Just to be clear, you left the existing gauges hooked up and tapped on the G3X input as well??
Electrically I didn't think this would work as both "gauges" are supplying a voltage source to the senders, this would normally be considered a no-no.

Sorry - missed that you wanted them in parallel - I was thinking Sending units. Walt is correct that trying to parallel the gauges is not easy. Using the existing sending units for the G3X is simple.
 
Put in a switch

I installed a switch in my panel to switch the sending unit signals between my vans fuel guages and my TruTrak EFIS. Works fine. John
