Hi All, New to the site and have a basic maintenance question about a 1995 K1500 Suburban. I told my mother-in-law I would help get her old truck past SMOG and it came back as needing a new Charcoal Canister (which the guy wanted $280 for). I can get one at NAPA for $80. My question is where is the Charcoal/Vapor canister located? Must be fairly easy to replace as the SMOG guy only wanted around $30 in labor to replace it. Any help greatly appreciated.
