Chevrolet Luv 89 carburetor problem

Great of mechanics, I have a Chevrolet Luv truck year 89, of so many repairs, the entire carburetor system was already confused, nobody knows where the hoses really go, it would be possible that they help me, either with some photo or manual to know the position and exact path of the hoses.
Of course, thank you very much.
