So I've finally completed the install of my Carter rotary pump and converting my system from mechanical fuel delivery to electric. The mechanical delivery was way more simple no doubt. I went to the trouble of using correctly colored wires and shrink tubed groups of wires where it made sense. Took me several hours to do this and was in the garage way too late last night. Most of the work was trying to figure out where to mount the fuel pump with the metal filter that came attached to it. Finding a flat surface near the tank with a run of length such that the fuel lines don't get pinched took some thinking. I finally determined that I would just mount it above the transmission. One tricky thing is the fuel pump has larger inlets and outlets than the normal dual carb fuel line size. I put in another fuel filter after the pump to step down the size. This one is in addition to the metal one that is before the pump and came with it. Is it OK to have a filter before and after the pump.
Location - this may change, but for now I'm fine with it.

At the lucky lab on Monday, Tristessa set me up with the perfect relay to take care of this conversion and a great diagram that even a dummy could understand. This relay takes power directly from the battery via a 7.5 amp in-line fuse. The relay takes signal from the coil.
The relay had no way to mount, so I got a thin piece of flat tin and JB Welded the relay to it so I could mount it to the firewall next to the voltage regulator. Kinda looks like it was meant to be there. If the relay ever goes bad, I'll have to make another mount, but this is nice and clean looking.
Here is the in-line fuse I used for power supply from the battery.
Sooooo how did it run?? Seems a little bit better, nothing huge or drastic as far as improvement, but I'm still feeling a little bit of pulsing or maybe I'm insane and it is just bumpy pavement. Anybody have a mile long sheet of glass I could drive on just to verify???
I"ll be testing the fuel pressure with my harbor freight gauge to see if my pressure has gone up or not.
