So I thought I'd post something helpful.
It's been a while since I searched this so someone might have beaten me too it.
Seems to me that every time I go looking for the part number an automotive pump that works for our sleds it ends up being a goose chase, and I end up scrolling through old texts for 2 hours to find it.
So without further ado
The pump that fits is a Spectra Premium SP1113.
I'm sure that there are other pumps that may work/fit better, but this is the only one that I know of, and it gets the job done.
One disclaimer though, I put this pump in my buddies sled last season, and somehow the supplied adapter harness didn't plug in correctly and one of the pins wasn't mated with it's corresponding mate, they were just side by side. It worked that way for the rest of last season and part way into this one. That's when we found my error, if you hold the connector just wrong it cocks the pins.
Hopefully others who have found other pumps that work will add to this
