You are correct on supply , delivery and control . The governor is mounted to the bulkhead , inboard of the fuel filter . There is a 1/4 black plastic hose coming off a Tee that heads to the air dryer control . Not sure about the blue 3/8 hose , I don't think I have that , will look this evening , get photos . On the '86 the braided hose from the top of the compressor routes directly to the AD-9 , whereas your system has galvanized piping involved . Not sure if that is original , but it has been working for you . As they say , if it ain't broke ..
