No seperate and/or additional gravity feeding if thats what you mean.
Return line from regulator still goes back directly into the fuel tank close to wwhere the feed pump picks up the fuel from the tank.
Upper connection on catch can goes back to tank as overflow and also acts as a breather.
Pics of the set-up are on page 33:

The idea of mine is/was that a zero-pressure feed pump (which is now the 944 pump) always supplies more fuel then the high pressure pump will be able to flow at 45 or 60 psi.
