Just bought a 2020 Tahoe

and now I cannot find a way to protect my gas tank from... well you know.. the elements … anybody know of any locking gas caps that will work with these "cap-less" systems? Any help will be greatly appreciated..

Welcome to the forum.

This came up a little ways back and here is a part number that was provided.

I think this is what you are looking for.

I just paid 3.89 a gallon for 87 oct. Tweekers gotta put meth on the table.

Holy shit! Paid 1.94 yesterday for 87. God bless Texas...

Yep. Blue vs red state. It’s all about taxes.

I have been thinking of a move to Texas for about a year now. Need to find a self storage facility to work at.

Didn't know that stealing Gas was still a thing... I thought it was like doing Crack.. sort of Passe'. Here on Long Island Pills and shooting H is all the rage.

These caps will keep contaminants out of the cap-less fuel system, if you are concerned. I have one and so does a relative of mine with a 2018 Silverado.

I saw before that they do actually make a locking cap for the cap-less fuel system. I've used locking caps before and they can be a pain but generally aren't all that bad. More or less they would be a "red flag" to show you that your fuel system has been tampered with, rather than a secure lock out against mischievous behaviors.

You pick - $5 vs $20!
