In my 360 with a header tank, I have the Grand Rapids EIS with a low fuel warning set at 8gals, very close to the 8.5 gals where the Pillarpoint avionics automatic transfer starts (transfer system is driven by my Princeton Electronics header tank probe).  That way I know very quickly if the auto transfer is not working.

 

On a separate circuit, I have a float driven switch in the header tank that actuates a different warning light at about 4 gallons.  This is my "last resort" fuel warning, independent of the other system (and powered by the #2 buss).

Hi,
just want to know opinions what volume  is practical for a "very last" low fuel warning (20 liter - about 6 gallons) in the header tank of a carburated 360. It is a standard installation with forward canopy and an electrical fuel gauge. In addition I plan for an automatic refuelling.
This very last warning is intended in case refuelling does not work and I am busy with other things and to give me a hint for immediate landing.
It works independent of the gauge.
Thanks
