Thanks again for the replies and suggestions for a cap to cover the fuel filler. I went with the Fernco PQC-102 2" Qwik Cap. I removed the hose clamp. I liked the two ribs on the inside diameter. When I installed the cap, it felt like it snapped on to be secure. Removal was easy even in the cold weather we are having. My local hardware store had them in stock. Great suggestion.

Now you'll have to find a cap for the key slot to keep it clear of dirt, water, etc.

Why did they go to capless? Is the concept of a gas cap just too much for some people to handle? Not like anyone is doing NASCAR splash and gos at the local Sinclair station.

I have a 2017 Silverado Z71. I found that the cap from a can of Krylon paint fits perfectly  and just a little snug on the capless fuel filler,  and its FREE.  When looking for a spray can cap, b

GM makes a half ass lockable OEM cover.
They’re about $15 on eBay or at your local stealership

I have 2018 Silverado 1500 Z71 with capless fill fuel tank. I am currently looking to trade in due to this. Chevy told me that they had to re-route the vent system (because it is located in the wheel well of all places) and that it is not covered by the warranty. I pay for engineers ignorance? $760 later I am back on the road. Then I see that all these new trucks have capless fill? I may have to special order a new truck???

Interesting.

Might you explain why they re-routed the vent. Did it get clogged somehow? Excuse for not covered by warranty?

Thank you.

Almost 2 years into my capless 2017... I bought a GM OEM cover, but only used it for a week or so because it was a pain to remove..That being said.. the filler seems to stay pretty clean behind the the filler door. At 32k miles, I haven't had any fuel related problems..so I don't use any type of cover.

I went to plumbing section of Home Depot and bought a ABS cap that fits perfectly. Did this for both the Silvy and the Tahoe. Sanded and painted yellow. Added a rubber edge from some tread slip belt I had and a Bowtie from an old keychain and it works and looks great.

Do you mind enlightening the rest of us why your capless fuel filler is so horrible that you are going to trade you whole truck? I personally find that hard to believe...Secondly, why would the dealer have to re-route your vent? To where? Why did it cost over $700? Finally, good luck finding another vehicle that doesn't have a capless system, seems they all do best I can remember from driving rentals...

I am off highway streets about 75% of the time for the type of work I do. I am in the oil and gas industry and in the dust and mud constantly. With the amount of wind and dust that we deal with on a daily basis, the dirt does pile up around the fuel filler.  Just imagine the vent that was put in the wheel well. I can't miss work by constantly having my truck in the shop. They re-routed the vent to under the hood. On why it cost so much? I don't know..  I have looked at all trucks now and only the Toyota Tundra and the Nissan Titan have gas caps still. The Ram, at least, has a sealed compartment for some of their models.

Well, you better hurry and get your horrendously outdated Nissan or Toyota before they update them in like...2050 or if ever. But I guess you wont have to worry about that crippling pesky capless fuel filler

A gas cap makes it outdated? I wonder what do you think of people still wanting keys versus push start?

Could have just sealed the door yourself or built a plug to put over the hole...

 

Suprised nobody at the stealership suggested replacing the whole assembly with a capped system from a 014-016 instead of rerouting gas fumes to the engine compartment?

 

kinda pointless to get rid of it now ain’t it? Since you spent the money to fix it?

Not in the least, my point is the entire truck is outdated...and for the record my '17 still has a key and I much prefer it.

Chevy has a tech bulletin on this, replace with locking gas cap 84308352

but I like the 2-1/4" rubber cap Ideal you find by searching chevy capless system dust cover

But just think how much time you will loose each week by not having a capless system. LOL

      2027 GMC Sierra: Official Discussion

      I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff".

      The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
