Ok, Bernie.

You didn't mention how much fuel you had in the main tank and just thought 
that 8 gal of so from your aux tank could have possibly flowed into the main 
tank and force fuel out the vent.  As you know even a hot day with full 
tanks can have fuels pouring from those external vents under the bottom of 
the cowl due to expansion along.  But, if it were only 1/2 full then not as 
likely a cause.

I have taken my pressure regulator out of the circuit and run up to 80 psi 
in the system (what the pumps provided without regulator) without any 
apparent ill effects.
