Hi, John....the pump specifies that it provides 43 gph @ 40 psi.  Of course,
if you are only drawing say, 15 gph, the pressure goes up.  See
www.topendmotorsports.com/engine/fuel/pumps/msd/   for pictures.  That is
not where I purchased it, (Summit Racing for $89.00), but that web site has
a good picture, etc.   My MicroTech EFI system provides a fuel pump relay,
so you can use a smaller fuel pump wire up to the relay, then the relay can
handle the higher amps with a shorter wire to the fuel pump.  If I installed
two fuel pumps, I will have to come up with some system to allow left,
right, or both. Makes plumbing and wiring more difficult, of course.  But we
do want to be safe.  I wish I could find a "twin" fuel pump setup that was a
two-in-one to reduce plumbing and wiring, but then you'd probably have to
replace both pumps if only one failed with a setup like that, even if
someone made a two-in-one unit.
     I also considered using one of the more expensive Aeromotive fuel pumps,
which have a lifetime warranty, and claim to "never wear out".  Might be
better peace of mind with a better fuel pump.
      Thanks for taking the time to offer opinions and advice, John.   Paul
