Bosch 044 is the way to go. I've got an in tank lift pump shifting fuel to a swirl pot that feeds the big Bosch pump. There is a 1/2" line from the pump to the rails and a 3/8" return line from the reg back to the swirl pot.

A few of us have gone for the Sard regulator. I've got one and so has Phil Neall. They are a nice compact unit and look to be well made. Reports I've heard is that because of their light weight internals they are very quick in responding to pressure changes (who knows if it's true or not but the turbo ricer guys like them).

The aeromotive is a good unit too.

Cheers
