That's what I was wanting to hear. Sounds like a reasonable answer and area
to investigate.

thanks...

I flew a Cherokee Six PA32-300 and finished up the flight and topped off
all
four tanks. Then noticed, an hour later that there was fuel streaming
from
the overflow port under the left main tank. The left outboard tank was
3/4
drained, and all other tanks were full. The fuel selector was on the
right
main at the time. Any ideas what the problem is? I thought all tanks
were
separate, but it appears that the left outboard may have drained into the
left main and overflowed......

All four tanks and tied to a common central passage (that feeds the
engine) with a spring-loaded ball valve in each line. The selector
pokes one of the valves off it's seat to open it up.

The head pressure in the outboard tanks can seep by a leaking ball and
make it's way to a "lower" point. I would have thought that it would
have filled up the selected tank first, but they will do strange
things.

Needs cleaned up/repaired. Not sure who does them anymore, have been
out the Piper game for awhile...
