Went To have my 1995 GMC Yukon smogged today and it failed the evap test. I guess that's the vapor that comes from gasoline allowed into atmosphere or something to that effect. The mechanic sealed of the canister and ran a pressure test and said the leak is in between the gas cap and where the hose goes into canister. My question is there any known or frequent areas that I should look at first. Where do I start and how? Any feedback would be appreciated. Thank You
