Bryan,
There are many a Lancair with just such an arrangement that has been
working for years. Try this: Use a 100 mph leaf blower to simulate
airflow out of the cowling and have another person crack open the gas cap and
see if they can feel air escaping.
Hopefully it is not located aft of the exhaust exit.

Is there
a way to test my Header tank vent line location to make sure it will work
properly when flying?
I installed it in the location of the plans and beveled it on a 45 like
the plans show. It sticks out below the fuselage skin about 1.5 inches.
Since my engine can only run off the header tank I would like to know
its installed correctly.
