After much experimentation, Jack and I ended up with the combination
of a Holley Blue fuel pump with the Holley low pressure regulator.
A common problem with fuel pressure regulators is that there's not
enough pressure differential between input and output to reliably
operate the regulator. The Holley Blue puts out 14 psi, and I have
it regulated down to a rock solid 2 psi for my webers.

With low pressure pumps, we repeatedly had a problem where fuel
delivery would shut down at the end of long straights and we'd end up
pulling the regulator to make it through the weekend. Having high
enough pressure to operate the regulator seems to be key.

What kind of fuel pressure reg. are you all using? I am now on the 2nd Holly
and with it set @ 3lbs in the pits, it moves from 2 to 8 out on the track when
we tested Friday. At anything over 3 I get a stutter coming on the gas out of
the slower turns.
