Too many idiots on this site think a gas cap is to stop siphoning.  How about stopping someone from putting crap in the tank to ruin the engine.  If you live in a perfect world this wouldn't happen but I haven't found the perfect world yet so stop being GM fan idiots.

Nice first post.

Maybe in other areas it happens, but I have never heard of people putting unwanted materials in gas tanks.  I used to drive a wrangler that did not even have a door for most of its life and I never had an issue.

Fuel cap locking part # 84308352

And FYI:

 

I checked out the part number for this and the above number according to the parts catalog is for fitting 2018 and is also listed under part ACDelco GT376.

 

The parts catalog calls out ACDelco GT377 or GM p/n 84214460 says it's for T1, 2019/20 (and probably going to be the same for 21). 

 

The 352 MAY fit 19/20? I don't know. The lock appears to be in a different clock position. That's the only difference I see, really.

 

I just did a dealer VIN check for my 2020 GMC, and they said I should get GM p/n 23389451.  I dunno what the deal is. 

 

I checked out the part numbers and it appears the 451 number is simply a supersession of the 460 number. Still shows a GT377 based on the information I dug up. 

 

It appears to be a locking PLASTIC cap. Not appearing to be super solid. So yeah, it's going to be only as good as a honest vandal/thief deterrent. Anyone who really wants to dump dirt in your tank...will.

Some in my area, mostly farmers have had trouble with their fuel pumps.  The cause is supposed to coming form dirt and dust entering due to no fuel cap.

It is a sealed system. The door now has a seal on it, not a great seal but it will keep out 80% of the stuff just floating in the air.

he's probably referring to kids doing stupid crap to random vehicles, like egging and toilet papering houses... maybe that was more of an 80s and 90s thing... but around here a couple months ago some kids hit a bunch of random cars with chocolate syrup.

I'll take chocolate syrup over eggs any day. My car has been egged before. The shells chip and scratch the paint.
