1972 california c10 carb and emissions problem

[Tony388]

Hi, I bought a 1972 c10 California truck with a l6 250 engine and a 3 on the tree. The problem is I bought it without a carb, so I am having a huge problem finding a California emissions carb for it. 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
