Typically wing tanks are filled to the brim of the filler neck.
Presumably that leaves some air trapped in the tank. Without knowing
the exact placement of the fuel vent pipe intake within the tank, it
is difficult to confirm an over pressure condition in this case.
Absent knowledge of how Mr. Rhine came to his "over pressurizing"
conclusion, it is difficult to substantiate it as fact. Might not the
venting fuel have been merely excess fuel draining from the tank as it
was designed to do when the tank is over filled? After all,
presumably it is the same fuel pump operating in both the factory
designed fuel system and the aux fuel system.


The Aux system used it's own fuel pump and it was tied in after the aircraft
fuel shut off valve.


So you're saying, that there was a new fuel selector valve placed in
the fuel line between the normal On/Off Cessna fuel selector valve and
the engine?

And the aux fuel system consisted of a fuel quantity indicator, the
aux fuel tank and vent, an additional fuel pump and electrical switch,
and a single fuel line leading from the aux fuel tank to the added
fuel selector valve?

The 172 SP has a fuel slector Valve L - B - R Plus A Fuel shut off Valve!

The Ferry Tank had a shut off valve fuel pump a hose that connected after
the aircraft fuel system shut off valve.

See Photo! Look by the aircraft fuel Selector You will see a Fuel Shut Off
Valve and The Fuel Pump with Switch.

What position was the position of the Cessna fuel shut off valve while
you were running on the aux tank?

The aircraft shut off valve was pulled straight out "Aircraft Fuel Off"
