Alex,

If a PO did install an electric fuel pump, the chances are better than
50/50 he did it in the most common way: in series with the mechanical
pump. If that's true, then your fuel problem is even more urgent: That
electric pump, when running, stresses the mechanical pump's diaphragm and
can, literally, fill the crankcase with gasoline if that leaks.
