Now that I've had a bit more time to think about this, I can imagine
very short extreme times when the flow from one pump might not be
enough for a big engine. To make this work, you'd want to put the 2
pumps in parallel. Are you sure Ray put them in series?
I think Ray is using 1 pump as a "lifting" pump (like a rabbit has), and
the other pump is the main supply pump. What he's doing, by doing this, is to
ensure that fuel delivery isn't an issue with his closely tuned t-4 engine
(where pressure deviations of 2 psi can cause a lean condition). He's been
playing with it for years, and found fuel delivery to be a problem (using
the stock pump).
