Pat---Before you continue on with the pump rebuild, be sure the fuel
gets to the pump inlet. With a half tank or better of fuel,
disconnecting the inlet tube should show the fuel to be gushing out.
Have somethng under this to collect it, and let enough free-flow to be
sure there's no obstruction, such as another in-line filter, as
suggested by others.
The fuel filter (the likely suspect here) should be placed before the
pump, tho some owners have one after the pump. In any case, it's just
the matter of continuing upstream till you find the flow too weak to
keep an engine running.
As you may know, fuel pumps are only necessary when the carbs are higher
than the lowest level in the tank. Older drivers remember such cars as
the Model A, that ran fine with only gravity feeding the carburetor. Or
so I've been told!
