The current configuration is:
Each tank (Main and Aux) has a dedicated filter and Carter 4070
electric pump on the outside of the left frame rail. Whichever of those is
powered, through a relay, from the dash fuel tank selector, feeds the
accumulator shown above. The two pumps' outputs are tee'd through check
valves into a single steel line to the accumulator. The check valves are
not necessary with the Carter 4070's, but who knows what substitutes i
might be stuck with in case of an on-the-road failure.
The accumulator has a return line from its top to the Aux tank drain, with
a skid guard over the steel line. That ensures that I always know that tank
has reserve fuel.
The high pressure filter and pump for the TBI are fed from the bottom of
the accumulator, and the TBI return is into the accumulator.
The Carter 4070's, as far as I know (remember, only my right ear works and
that only about 1/2 well), are very quiet. The high pressure pump is
slightly more noisy, but not enough to disturb HER. No neighbor has ever
complained about pump racket. If they did, I'd probably crank up my
TroyBilt generator so they couldn't hear it. :-)
This arrangement has worked flawlessly, with no vapor lock problems for
over 5 years now.

You’re making a great case for FITech’s Fuel Command Center, which partially functions as a surge tank.
