I have a 1990 GMC Jimmy s15 4.3l 4x4, I noticed when I got this car that the vacuum hoses were disconnected and so I wanna make sure I have the correct ones on the right path because the diagrams and hose routings are completely worn out and faded. So I made a diagram of how I have it currently.

edit: so from the reading I’ve done on this site it seems I need to switch the Vac Acc with where the hose going to transfer case is, so I swapped those two hoses spots. And we will see if that’s right
