My "rail" is the line to the throttle body, so it's dead-end. I could use the third port for fuel pressure. What kind of regulator do you have? All I need now is a pump than can be plumbed in series ... Jim S. atlasyts@bellsouth.net wrote: >Jim and Bill, I have a 3 port regulator. The fuel line from the tanks goes to the 2 parallel electric pumps, from the pumps to Y block and than single line to the fuel rails. the outlet from the fuel rails goes to one port of the FP Regulator, and than return to the fuel tank.
