The intent of an FMU is to be simple and cheap. It generally works well for lower boost applications. 7-8 psi would probably be the most you wil want to run as fuel pressures will start becoming very high beyond that.

Injectors are not necessary as the FMU is a cheap way to get around the need for bigger injectors.

The OEM fuel pump's capacity is ok for an FMU, but depending on how old the fuel pump is, it may not be able to flow as well as it did when new. It might be advisable to get a new high flow pump if you have any doubts.

You retain the factory pressure regulator and the FMU goes inline on the return line after the OE regulator. So in short, no...you don't need a new regulator unless the existing one is not functioning properly.
