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
