Jim and Bill, I have a 3 port regulator. The fuel line from the tanks goes to the 2 parallel electric pumps, from the pumps to Y block and than single line to the fuel rails. the outlet from the fuel rails goes to one port of the FP Regulator, and than return to the fuel tank. One of the ports of the FPR is capped.
I would not install the pumps in series.

Mark How does the 3 port work? One line in (fuel supply), one line out to injectors,
and line from regulator back to tank? in this case wouldn't the line from regulator
to injectors be dead-ended? Bill
JIm,
I'm using a 3-port Mallory fuel pressure regulator. It is supposed
to be capable
of regulation between 3 and 65 psi. They have other
models as well. See

I'm still wondering if:
Can any (or all) electric pumps can be plumbed in series and pass fuel
when shut
off
Are there any regulators that can be adjusted as low as 25 psi
Does anybody have these answers for me ? ... Jim S.
