How do I get this to fit my 2017 Chevy Silverado 1500. The insert is bigger than the opening.

Return it. The item description as to what vehicles it fits is incorrect.

How can I attach a tether to a locking gas cap like this one?

Pluse this cap to me my is good but twisting it with the key is interest you need patience,,the evaperation system of the auto Is import. It must have a good seal. Be careful turnong the cap too because it yrouble getting if too tight. Try turning key with no presure... If thats not enough the try it with presure. Remeber the direction of the cap.. Alternate until to get the cap off (no presure/presure in the same directtoon slowly,,,).
