Rob,

 

One way to get your head right is to realize that the header tank is the main fuel tank that is responsible for running the engine.  The wing tanks are merely auxiliary fuel supplies.  One way to relieve workload is to have some way to keep the header full or near full without dumping fuel overboard because you forget to start the timer.  Two sensors, say about 2 gallons apart, can assure that the header is always full enough for your emergency flight range.  If the low value is about 8 gallons, that's at least 45 minutes at reduced power if the tank is properly baffled so that you get to use all but the last gallon in descent (or maybe ascent in the case of a go around).  Forget about those that have selectors that use the wing tanks directly - especially if they failed to include slosh doors and fuel containment compartments in the wing.  In level flight, the wings can be completely drained by filling the header.

 

So, two floats (hi and lo) and some simple automatic (with manual override) system to keep the header full is desirable.

 

If you are like wild Bill and intend to fly across the outback or wide seas, then a more complex system to give you access to every drop might be more appropriate.

 

Good Luck,

Another request for those who have built the L320/360. I am just beginning to build up my header tank, and am thinking I might install a float switch to operate a “Tank Full” warning light when transferring fuel to the header tank. I am interested in comments from other builders about what you have done, or even better, what you wish you had done, in setting up the fuel transfer system.
