So engine died this past sunday and had to get towed back....fuel not getting to carb - while troubleshooting I found a carter electric fuel pump under the floorboards, does a '79 S&S have 2 fuel pumps or is this something that a former owner installed for some reason?

I think a po added it, the mechanical pump might be bad thats why the electric pump was added...

Sometimes an electric fuel pump is added upstream of the mechanical pump to cure a vapor lock problem.
