05 equinox- evap canister
 

Hi, Im knew here and have a problem with my 05 equinox evap. We got the code stating it could be 4 or 5 different things, put knew gas cap on a the purge sylenoid under the hood. Just bought the charcoal canister and cant get the old one off because of a clamp that is part of the lines. Does anyone know how to remove the clip?? Thank You
