Almost assuredly some previous owner took off the mechanical fuel pump down by the right-hand-side of the engine (there must be a blanking plate over where it would be actuated by the camshaft), and installed the aftermarket electric fuel pump which you have shown in your pictures. As has been said already, in many cases people left the original fuel pump and only used an electric fuel pump as a "priming" pump, also useful for situations with vapor lock.

You have a few choices:

1) Keep the setup you have and rebuild or otherwise refurbish the Stewart-Warner (IIRC) pump you have. That's not a stock Packard item, it is aftermarket, that's all I know.

2) Get rid of the electric pump, and as some have suggested, put a mechanical fuel pump in - I believe you can get a refurbished mechanical fuel pump from Kanter Auto (www.kanter.com) or Max Merrit (packardparts.com), or many others. Best to call them.

3) Install a mechanical fuel pump and an electric fuel pump to act as a priming pump. There are a few pumps people have used, there are other threads to that effect here on this website, do a search for electric fuel pump.

4) You can replace the electric fuel pump you have with a new one, again do a search for electric fuel pump on this website.
