the pressure regulator is on the outlet end of the rail, as it works by relieving the excess to keep the pressure constant in the rail...HTH.........drQ

Finally starting to hook things up on the 20V swap, and not sure which line  
on the 3B fuel rail is the feed and which is the return.
Is the vacuum diaphragm controlled end the feed or return?
