Re: Electric fuel pump vs original mechanical fuel pump

Typically the vane type pumps must always run as a standard pump can't pump through them. In the rare occasion that I've had a Packard with an electric pump (which is only if I bought it that way) it is always the diaphragm type which has check valves just like the mechanical pump so will have flow whether powered or not.
