who ever had the truck befor me did a number on switching the lines in all the wrong places if anyone knows where i can find a diagram please let me know, i bought a shop manual in hopes of finding one but in the 2400 page book i can find everything but that lol so if anyone knows where i can get my hands on a diagram please reply to my post
Not sure what year truck you have. If it is pre-emissions, then this won't help. My truck (1982) has a color coded vacuum line diagram under the hood right next to the emissions data sticker.
The vacuum diagram on my 94/95 was on the underside of the hood near the drivers side hinge. The Haynes manual has vac diagrams for some models.
