An AN line between the tank tops to prevent vapor locking, and just use one internal or external 58psi pump to deliver fuel to the rail. Eliminate switches and other pumps all together. The one sending unit doesn’t care if it’s 3/4 of 20 gal. or 40 gal. Run the manifold pipe in a steel tube welded to a cross member for duribility. I had 55 gal. drums that caught water from my downspout. Fill one drum and they all fill equally. Pull water from one they still keep the same level. Other than protecting the manifold pipe or line, this in theory sounds like it would work. Save coin on valves, switches, sending units, etc. Just a thought. Open to why not.

I thought about this idea on my crew cab , but it would be the lowest thing hanging down . not sure if you have an issue if you could ever stop the fuel flow to the ground.
