Does anyone know where I could possible find one? The other problem I have is, I can't figure out or find how the vacuum hoses go to the carb. I bought another l6 250 engine that had a 4070022 carb on it, so I wanted to put it on to try and start the motor, but I have one vacuum hose I don't know where it goes. Is there a diagram somewhere on this? All I see is regular emissions, not one with the California emissions pump. Any help would be a great help. Thanks

You need to find the Maintenance manual. They are for sale at places like ebay. Check around. One of the members here uploaded them, and yours might be in that group. The vacuum diagrams and other information you need will be in it. It is important to have the equipment hooked up correctly, if only to make sure that you don't have fuel fumes in the cab, or get into problems with the fuel tank because of improper venting. I'm not sure exactly when GM went from California/Federal to just US emissions (I think in '75, though, but I'm only certain of that for cars).
