Quick update.
Dropped the fuel tank today, got back into the second pump install. Tank drop was minor, set the fuel prime to 1 min and she didnt take long to pump out the 14gal of fuel in the tank.

The Racetronix pump wiring bulkhead is an awesome piece. If you want a heavier gauge, high quality wiring solution that is made for regal tanks, this is it. Huge win. The dual pump base plate worked well, needed some tweaking but is not a bad piece. I wouldnt use it again, I would make my own, but lesson learned.

So popped out the wiring harness, and stripped off the return line as a tab for the stock pump was in the way.

Got the tab removed and sized up the bottom plate.

The wiring harness bulkhead needed to be pressed on, I used a socket and C clamp. Was pretty easy. Unfortunately no pics. But here is the almost final product.

I eventually rounded out the holes in the bottom plate to get the pumps closer together. Wired up the pumps to the harness and went to install.

It was at this time I discovered that it was not going in the tank with the fuel level sender on the hanger.
So this happened.

I'll have to revisit this later. For now a custom math channel to get the holley to calculate fuel burned. Yay Holley EFI.
Fired the tank back in, tested and I had to back off my regulator almost all the way to maintain my 43psi fuel pressure. Hell ya!
Next is the ethanol sensor.
