Stop over filling you gas tank to get the last 1/4 gallon in the tank. It over fills the tank then goes into the charcoal canister. Then never comes back out so the canister can't breath thus let air out when you fill the tank.
It was taking forever to fill my tank and had to do it super slow to get it to fill. Now it works normally.
Ever try filling up your lawnmower with one of these new portable gastanks with no vent cap how it takes forever. Same effect.
Easy fix. I did this less then $20 from the scrap yard. Going on over 1 year. Look for the remote hose assembly that will tell you it's the newer updated setup.
1999-2006 Chevy Suburban, Tahoe, Silverado, GMC Serria Suburban, Yukon, Denali. Most other years are the same. The 6.0 has to be basically 6.0 for the canister I was told. Caddy's and Denali's both used the same.
