Jerry,
You forced me to do a sketch. So, here it is. Mark ---------------------------------------
Mark, why do you choose not to return fuel to the tank instead of to the
selector valve? I have been to 17000 feet in Fla on auto gas and when I
landed the tanks feel very cool to hand and this is the fuel that the
pump sees rather than the elevated temps coming back from the engine bay.
I have run tanks dry above 10000 and the engine quickly fired off as soon
as I switched tanks so returning fuel to the tank has passed any test I
can think of. The fact that the system apparently boils someplace along
the way during ground shutdown but quickly clears when the pump is turned
on says that if I had a small orifice that it probably would take longer
to bleed the vapor rather than returning it to a cooler tank.
