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.

Bernie,
Here is a thought - assuming based on your inspection today that all
fuel
connections under the cowl are tight and no hose leaks. IF your
tanks has
the external tank vent line that Van calls for - is it possible that
during
your fuel transfer that you may have transfer sufficient fuel to
over fill
the one tank and to cause some excess fuel to flow out the vent
line?
Recall the vent line exits (at least on my RV-6A) right behind the
bottom of
the cowling. That's what I would bet on.

Hi Ed,
Thans for the thought but keep thinking! My return tank is not half full
so do not believe it was blowing out the standard Van's vent lines.
Can not find any loose fittings nor leaky hoses.
How would you pressurise the system to a higher pressure to see if
something developes without damaging injectors or regulator?
Right now, my best guess it that there was a dry joint that leaked. Had
not run engine in about 2 weeks.
Bernie
