It is my understanding that the wings, in a header tank 360, don’t
NEED a fuel level system (aux tanks).
I know mine doesn’t have a level system in the wings, and I know of others
too.
My wings feed to the header with ¼” lines. All works
beautifully, and I wouldn’t change a thing. I know my burn rate, and if the transfer
pumps quit transferring, then I’d know what emergency fuel I have in the
header. That’s plenty for me.

Re my earlier reply attached to your original post... while the measure and
time approach to determine fuel level might have worked for Lindy he probably
didn't have FAR 91.205 to deal with. The minimum equipment required for
VFR flight under that regulation includes a fuel level gauge for each tank, so
you will still need to deal with some sort of sensors for the required
gauges. Someone suggested a pressure sensor as an alternative, and I'm
sure there are others that are easier to retrofit in closed wings than your
typical capacitance-type fuel probes, which would be a real challenge (if even
possible without major surgery.)

I am building a Lancair 360. The previous builder already closed out the
wings. He used the 1/4" lines to feed to the Header Tank as the manual
suggests. And He never installed the fuel probes.
Can anyone suggest a way for me to test for leaks in the wings?
What can I do to get a fuel level reading without cutting into my tanks to
install probes?
