I'll try to remember to send it this evening. If you don't receive it
drop me an email using the "reply to author". My profle email is
valid.

The only picture I have may not show all the details and the system is
long gone.

The basic idea was was as follows. I had a 50 gallon tank in the bed
of my Malibu station wagon. A marine bilge pump fed the water to the
base of a 2 (?) inch pvc stand pipe that located on the hinge line of
the tail gate. The base of the stand pipe had 2 ports - the inlet,
and the outlet to the glider fill hose. The top of the pipe located
on the tailgate glass latch pin. About 3 inches from the top of the
standpipe was a T fitting and a pipe fed from that T back to the top
of the ballast tank.

The recirculating stand pipe will only work with a tank system. For
use off a faucet I had intended to design a stand pipe with a header
tank and float valve but never needed it and never built it.
