If the pump is truly pushing 3 psi, I'm surprised that you are having this
issue. I regularly ran 5 psi into the HS6's on my vintage race TR4, with no
overflow issues whatsoever, even idleing in the paddock. One of my friends runs
as high as 7 psi on his vintage race TR4. The only time I had fuel coming from
the overflow was when 1 of the floats failed and sunk. This is happening more
and more, at least at the track, due to some of the additives in the gas. The
regulator of choice is the Holley, but to set it, you also need a fuel pressure
gauge. I'm not a believer in the little round disc regulators that you adjust
by turning a dial.
