Bob---To avoid fuel starvation, the electric pump should be mounted at
least as low in the chassis as the mechanical pump.
It's best that the mechanical pump is out of the loop, if that's what
you were implyng with the "T" you have.
To be sure that there's no restriction in the bottom of the tank, or the
fuel line leading to the front of the car, disconnect the fuel line at
the pump and let it drain into some sort of pan. Let it go for a length
of time, so you can observe if the flow slows down. (It shouldn't)
I installed one of those inline, clear glass filters AFTER the pump, but
without the filter cartridge. This was very helpful in making sure that
all of the air was purged from the fuel line. You should see no air
bubbles in the fuel, enroute to the carbs.
When using an electric pump, a pressure regulator set to no more than 3
lb. is sometimes required, to keep from knocking the float valves off
their seats.
