Question about 1989 Chevrolet C/K 3500
The larger diameter fuel line is the fuel supply line, and the smaller diameter fuel line is the fuel return line. The distributor for that vehicle should have no vacuum advance on it, and the distributor should look like the one in the image below.
The fuel pressure for that carburetor (or for any other carburetor) should be around 7 psi only, and if the fuel pressure exceeds more than 10 psi it will start to push the fuel past the needle and seat and it will flood the engine. If you are going to use the same fuel pump that was used for the TBI then you will need to install a fuel pressure regulator, preferably one with a fuel gauge, and set it for 7 psi.
Of course you do know that the vehicle will never pass an emission test once you have converted it over to carburetion, and the MIL (Malfunction Idicator Light) or "check engine light" will most likely be on constantly. Let me know if you require any further assistance.
