    Hope somebody can help me out. I need the vacuum diagram for my 1997 K1500 Suburban with the 5.7L. Mine is so faded I can't make it out. I've searched the site, and found nothing. I did find that the stickies mentioning diagrams lead to closed pages or you can't access the info due to password protection.

    Thankyou, dipstick, for trying to help but that diagram doesnt exactly match my truck. On what they have labeled as the purge vacuum diagnostic switch. I have a third nipple pointed out towards the passenger fender. All thats on the nipple is an elbow and I cant find any lose hoses that would connect to it. The truck doesnt act like it has a vacuum leak but something has to go there. If anybody has a 97 K1500 Suburban with the 5.7L could you take a look at yours let me know?
