I am looking for vacuum line pattern for a 1993 Ford Ranger with a 4.0. It has a broken vacuum line that I can't figure where it goes. The line comes off the front side of the main vacuum on the intake and has about 12 inches of hard plastic line on it. Also the computer is pushing code 313 secondary air injection not by passed???????????????

 

on the top of one side of your airbox there should be two little nipples for vaccum hoses, just a suggestion for you to check
