^he's right...

You're fuel consumption will not be aided by a larger volume of space for the pressurized fuel to be in.

The injectors will either exceed the feeding capacity of the pump or they will not...

The reason every stock turbo'd car has small diameter piping is because it's not the volume that counts anymore... it's underpressure... so the smaller the piping the faster the turbo can pressurize the system... once pressurized the only thing that will stop it from flowing enough air is the supply capability of the turbo... not the size of the piping.

So essentially all a larger fuel rail will do for you is take the fuel pump longer to come up to pressure at start up.
