I plan to draw from both. Both tanks should draw evenly, but if they dont for some reason, I want to know about it before I get stranded...
You going wifth offshore style senders, or just the standard float type? It's been my experience that the float type give you an "idea" of where your fuel is but probably wouldn't be accurate enough to show small fluctuations between left and right. You might check with Rex about the "Centroid" style senders seen below.

They have small calibration screws that allow you to dial in you empty and full resistance settings.

Chris, im not sure what senders Ill go with. I want the gauge to work well though, otherwise i might as well stick with the ski flag pole method!
Ill check with rex when the time comes... I had no idea there was more than one type...
