Install two float switches.  One switch is for full indication.  The other switch is about half way down at a level where it will turn on when you have 30 minutes reserve fuel remaining.   Now you can develop a auto circuit to turn on your pump when that switch is activated and the top switch will turn off the pumps when full.

 

 

Ron Franz developed such a circuit. I obtained a copy of it and expanded it to cover all three tanks, header and wings. It worked beautifully.

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.
