hard questions all.
first off ALL FPR , stock have no factory published spec. so you'd have to reverse engineer that. (flow ratings are not PUBLIC)
and the stock FPR is designed to work with 60 psi max. (called shut rating or dead headed)
all race shops sell this stuff, summitracing dot com. and JEGS (ignore carb types)
lots:

bench testing, ok.
now that is harder, "how would i ever make up that custom, suzuki rail fitting. ? "
the FSM covers the on car tests,
as does my page,
http://www.fixkick.com/sensors/tests/FPress-reg1.html
your first test fails, hard. total failure.
and is because the pump is too powerful.... the FPR can not flow fuel that fast or at that volume ever. it was never intended to do that, ever.
so id put in the 60psi reg near say the tank, (safest spot away from spark and collision damage)
controlling the rear stream back max pressure, means you control max flow. at all times. (when overloaded)
once the line pressure is limited to say 55psi (best)
then you use a simple hand vacuum tool pump on the vacuum nipple.
we key on 3 times. (primes pump)
then see pressure on the rail gauge.
i remove the vacuum nipple, it must not leak gas or the FPR is DEAD stone useless.
the
my hand tool test it at 3 vacuum points.
no vacuum what is fuel pressure.
next at 20" HG vacuum what is pressure.
last at 25 inches. HG. what is fuel pressure.
that is the test in the FSM too, the 96 book is free and online, click books on my main screen.
i made graph just for the FPR, (only one there is) and is all you need to test any suzuki g16b FPR.
see key on pressure on the left side?
now look to the right side. max vacuum there,.. you pump the handtool and get the pressures seen here.

the key on pressure sets the base lines for all the others. so adjust your expectations , from the base pressure
mine was 36psi, but im at 500 ft altitude.
what you do is see that what ever keyon was (PSI). the fuel pressure drops by 6 PSI to idle vacuum . see?
cheers.
