varijet vacuum lines

[tphsmith]

can anyone help me with locating the correct line conections on my 81 half ton 250 CID motor for the vacuum lines, from the carburator?. this truck I bought off a used car lot and every weekend and night after work I am trying to get the motor to run right. I need to see pictures or a diagram for the vacuum lines off the carburator to where the lines correctly go. yes there is a diagram on the radiator mount but pictures will help me alot better please. Or can you suggest a web sight to see that shows very good detail on the lines and the correct places where the lines route
