Facet have loads, on closed loop systems I use 40106 but there are performance versions and you can pick anything from 3psi and a trickle to 30psi and flowing literally gallons a minute (imagine trying to burn that much fuel!!!!).
They are also all fully sealed, solid state and only kick in when pressure drops and they need to - not rotary pumps so they don't need to run all the time. Two wires to connect, stick it anywhee near the tank within about a foot above max of the fuel level and bingo, supply issues solved with fuel coming out the engine bay like a fuel pipe.
The pump modding I was on about would be on a stock pump, send it off to be modded (not sure if they upgrade the pistons, will reseach it further) and it comes back and still bolts on.
Yes - to lower rail pressure as it's controlled by the electronic actuator on the pump a remap would be needed. I'd imagine weaker springs in the injectors and bigger nozzles would be required to get you back to the same or better flow, but at a lower pressure with less drag and strain on the pump and less fuel leakback.
