oh you might have the wrong engine in mind its got a cfi unit with one full line in and one out its got an injector in the centre bolted on above the throttle body there is no fuel rail there's a throttle sensor bolted on the side with a little arm on it that moves in sinc with the throttle lever on the t body and another sensor that looks like a solinoide that has a little rod at one end and a block connector on the other its bolted behind the lever on the t body when the t body is closed it rests on the rod pushin it back in about a centimeter when the throttle body is open the rod comes out that centimeter again i'm guessing its an idle sensor
