Links?I removed the OEM filter, fitted a metal canister fuel filter in the tank<<<<
I also removed the diaphragm fuel cut-off valve and replaced it with a mechanical spring-loaded one-way flow valve.<<<<

There's some documented fuel pressure readings on this page:

'Ceptin' gravity, of course.At the time, there really wasn't anything available for aftermarket that low.
I guess what I'm actually asking is: what is the relative height between the tank and the carbs?
Got the McMaster-Carr number by any chance?got the check valve from McMaster-Carr.
An Artesian well of sorts. I like it.
Just thinking, why wouldn't a pair of simple tees work as well? Add a tee to the output of the pump that circulates to the line ahead of the pump.
Thanks.Uncle Phil : Sorry, I don't but it was one of these : Check Valve for Fuel
These are low pressure in-tank automotive fuel pumps, like used on a 1986 Accord with a carburetor. The needle & seat on a ST1100 should be able to handle 4 psi . Same type of needle & seat that is used on the Honda Accord carb.
Here are the pump specs : Low Pressure Auto Fuel Pump ( 2-4 psi )
At full throttle you only need oz. / minute , not gallons / minute. These pumps are plenty good to satisfy a ST1100.
No regulator required - not a high pressure F.I. pump, only a regulator and return line is required for a F.I. system. The pressure speced ( 2-4 psi ) for the pump in the link above is the dead head pressure.
A F.I. pump has a dead head ( speced ) pressure way above the F.I. fuel rail operating pressure, that's why a regulator and return line is required for F.I.
See the spec on this FI pump : FI pump specs
