OK so I keep getting po442 small evap leak. I smoked the system using the the evap service port, I noticed a lot of smoke near the gas cap area. I’m assume because I didn’t pinch off the vale on the canister, and there’s a line that goes up to the neck to the canister. When I finally pinch the line off couldn’t find any leaks afterward. Is this normal? Its not a gas cap problem. I believe this is normal
