I will be posting pictures of some of the items on or around the intake manifold and CIS that I am unfamiliar with. Maybe you can help me with the identification. I feel that I know what the fuel pressure regulator looks like. Does it work after the fuel return line from the fuel distributor? I think that I have read that fuel pressure is regulated after the fuel return from the FD. I imagine that to find the correct pressure inbound to the FD that I can open a threaded plug on the bottom portion of the FD and see if I can measure the pressure there. I'll try to get that done by tormorrow. Thanks for your reply
