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,,,).

This works on a 1988-1998 k1500

I have read a lot of bad reviews on this particular gas cap. I have to say people can't read, This product works perfect if it's used properly. I'm happy with it, and I don't have Crackpots trying to suck gas out of my tank. Again great product if used correctly.

Great! Very secure

Had someone in our apartment complex stealing my gas, have had no issues since replacing my gas cap with this! It can be a little annoying to unlock, but otherwise I've had no problem! And that could very well just be my clumsiness with locks at work!
