Robert,
I have a similar engine setup with the same EFI system. My install used a swirl pot in the little box compartment just in front of the rear wheel, the opposite side of the battery box. It is the shape and size of a beer can, maybe a couple inches taller. It is fed with a low pressure, high volume pump and all the excess goes back to the tank. A Bosch 044 high pressure pump pulls off the bottom of the swirl pot and feeds the fuel injection. With this setup, I have never starved the motor and have run it as low as needing almost 18 gallons to fill it up. In theory, that left a gallon in each tank if they are truly 10 gallon tanks.
On the Eight Stack system, the feed comes in one side, raps around and then feeds the other side. We found on the larger cu. in. motor, I was running too lean on the second side. The solution, for mine at least, was to "T" on the feed side of the throttle bodies and feed both sides and "T" off the back and return back to the tank. According to the ECU and computer, my lean condition went away. The issue only occurred under heavy acceleration, full throttle basically but it was enough to concern my engine builder.
I thought of doing something like you did, I just didn't want to pull a tank and re-work everything. Great work as usual!
Mike
