Bob-
You will need a fuel pressure gauge capable of measuring fuel pressure
down to 0 PSI.
It would be installed between the fuel pump and the carbs. If you are
running a stock mechanical pump, you should be somewhere around 2 1/2- 3 1/2
PSI. one should also check for fuel volume as well as it is possible to have
fuel pressure within specs but insufficient volume. You should have a
relatively full stream of fuel exiting the line each time the fuel pump
pulses. If not, you may have blockage in the supply system. The poor man's
way of observing all of this is to get a see-thru fuel filter and install it
in-line with the fuel line just before the carbs, then you can observe the
flow without a gauge.
Good luck,
