I don't think I've ever seen a problem with capless gas tanks, Ford car have been doing it since 2007 or so and I haven't seen a failure yet. 

 

Just bought a 2018 Silverado and I love not having a cap.

if you shake it more than twice, your playing with it.

You can buy a cap to plug it. Don't know why anyone thought this was a good idea.   Sent from my SM-G920V using Tapatalk

Emissions. A loose gas cap pollutes more. The less human involvement, the less that'll go wrong. Not saying I agree with that but I know that's their logic. Ford has used this system for several years

Picked up GM's locking gas cap from my dealer. Because I had complained about the potential dirt and water problems with the capless system they gave it to me for free. In any event I took it home and tried it on my truck. It seemed to fit snugly but when I went to take it off, that was another story. The top seems to get caught on the inside of the gas cap and it can be a struggle to get it off. I guess this was GM's idea of a quick inexpensive fix from complaining customers. I will have to make some modifications on this cap to make it fit properly for removal....

I got the same cap for free a while back and also found it to have a poor design when it came to using the lock. I guess I'm lucky that the plastic on the underside of the lock broke yesterday. I now just sit the cap on the circle like you would with Dogditcher's PVC solution posted up above.

So any ideal on what the difference is between the 2017 cap and 2018 cap wouldn't think there be much change in the filler.
 
 
 

Are they different? Capless started with the 2017, I’d assume 2018’s are identical, no?

Nope there isn't just a updated part number but the cap it self is the same. wouldn't waste the money lock is really cheap breaks easy.

I bought one for my 2017. Ya, It’s a piece of junk. Tough to unlock and get off. It now sits in my bench storage compartment.

I was just wondering if something changed between the 2017’s and 2018’s after I read that post.

Man if only GM paid engineers billions of dollars to develop working products prior to releasing to the public....

Get better neighbors?
JK, I don't see an issue as one can do that even with a twist cap.
Had that happen many years ago by the boyfriend of an ex-wife,
Had to drop the tank and clean it out - I saw the sugar before I started the 1978 truck.
I do wish Chevy had an automatic locking gas cover when the doors are locked like my 1990 535i BMW, though, same as my 1990 525i, 1990 750iL.
Interestingly enough, when I bought my truck last year, first thing they had to do was replace the capless fuel filler cap.

I have capless fuel filler on my 2017 Buick Invision. I agree I don't know why anyone would want this. Didn't have the car a month when I inserted filler nozzle and knocked off spring loaded cap which fell down the filler neck. Happened right a time when I was going on extended trip. Was concerned about dirt and moisture Wound putting plastic bag over it until I can fix it.

Did mine about a year after I got my '18 ME Silverado.

Got mine at Lowe's.  Keep the worm clamp for a future project or pitch it.  Measure your fill port diameter first, so you get the correct size.

GM p/n 84689444 / AC Delco GT378.  Comes with a clip that installs in the gas door hinge hole so you don't lose the dust cover (filler cap).

      OCI, not when but why?

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
