Tanks Inc-who's using it for non fuel injection and a few other questions

Yes I have the whole Tanks Inc setup in my '69 Dart. Real nice powder coated tank, and high quality, quiet, Walbro pump. I ran new lines to and from an Aeromotive bypass regulator and my 780 Holley. No more vapor lock, or endless cranking to get fuel into the carburetor! Only problem was that the fuel gauge sender was junk. I pulled the tank again and installed a linear sender from Classic Instruments (p/n SN39T8 for 8" deep tank). It's slightly better than the Tanks Inc one, but still not too accurate.
If I recall, you have to set up the sending unit individually for each tank. I followed the instructions and mine has been accurate as hell. .....maybe I just got lucky. I do remember the guy telling me the set up was pretty important.
