Questions on installing Pierburg pump '76 911

[billh1963]

Looking to install the Pierburg replacement pump on my '76 since the original style Bosch is NLA.

Porsche 911 (1974-1989) - Fuel System - Page 4

Fine print says "Minor~modifications may be required for installation"...no *****. More than minor if you ask me. Look like I have to cut the wires since the new pump does not have a socket for the plug. Also, looks like some plumbing is involved.

For those who have done this I have a couple of questions....

1. Which end is the pump input? I hope its the end away form the terminals since that is the correct size for the hose from the tank

2. What do I do with these "spare" fittings? Apparently, the pump can be adjusted for 3.0 bar and 6.5 bar pressure. What pressure do I need?

3. As you can see on the original pump, the outlet side is smaller than these fittings on the Pierburg. I guess I need to find some sort of adapter to fit a smaller fuel barb?

1.The input is the side without the electrical connections.
2. The spare fittings were not used in my case. I have 3 left over, including the one shown threaded in the top.
3. Remove the banjo off the output side of the original pump. It should thread right into the top when you take out the shown fitting.
