IIRC With CIS-E you should find a little rectangular gray box (electronic Fuel Pressure Regulator) attached to the fuel distributor with two screws. It also has an electrical plug going to it. The CIS has a mechanical Fuel Pressure Regulator (AKA Warm Up Regulator) attached to the engine block and it has 2 fuel lines running to it from the fuel distributor. later, dave
