I have a new 2017 Denali I've noticed that without a gas cap there is potential to let dirt and water into the fuel system. I have seen water puddling up in around the filler hole as well as bit of dirt. Any thoughts on how to seal this up a bit better.

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

Never seen the "gas cap less" feature. Can you take a pic of it? does it still have the "threads" to screw a cap on?

My 2015 Denali doesn't have it, but it is on my 15 Corvette and I have not had any problems -but it isn't driven in the winter or truck environments.

On the Corvette, the spring loaded trap door has a perimeter gasket seal -does the Denali have the same seal?

If so, it seems to shut pretty tight, which should keep the water and dirt out?

But I guess if there is dirt on the outside of the flap, it could be pushed into the tank.

Maybe just making a thin rubber flap that would cover the face of the filler trap door would help?

I know the grand Cherokee didn't have a gas cap a few years ago. Not sure if they ever put them back on but I agree it's foolish not to have one. What's the reason to not have it, weight reduction? :rolleyes:

So a lazy person doesn't have to waste all of 2 seconds to take the cap off. I have a lockable gas door on my '14 and had one on my '98 and I just place the cap and keys on top of the toolbox so I know I won't forget it.

Yeah. But you have to spend another 2 seconds to put it back on. Geeze, a whole 4 secs of my life wasted each and every time I have to stop for fuel. Wait, isn't there an app for that?

 

I had the capless fill on my Raptor. Never had a problem with it. But it did have a seal around the flap door to prevent water from entering the space.

 

I have it now on my 17, Hope there wont be any problems in the future.

It's not about owner laziness and the added 8 second it takes to take off, put on the cap. Probably more about idiots not putting the cap on tight.. then the truck throws a code, and they head to the dealer. It just waste time for everyone. Like said above, less human involvement is good.

      Is the 6.2L L87 in a 2026 Sierra 1500 ok?

      By asilverblazer · Posted

      What meaningful corrections were done to fix the "machining errors?"   I bet nothing, because the 6.2 is soon to be obsolete. Why would GM implement any fix let alone an "expensive one?"   Until someone can provide any convincing information that GM did ANYTHING to correct the engines - the 6.2 is no for me.    Which means keeping the 2016 Denali longer until the next generation (6.6?) proves itself.

      If my father took a Sunday off. We did the Sunday drive. Usually stopping at a Geno’s for dinner that we eat in the car. Six of us with my little sister up front. It was always a Buick growing up. In New Jersey you couldn’t get lost. Not like Texas.

      I suppose I am Atlas. It can always be worse, eh?   I had a friend once that rolled one payment into another until he was paying the price of Benz for a 10 year old back marker. Wouldn't be often you start a new payment the month following your old one.

      I still enjoy the drive   Some people fish when they retire; some golf. I drive. We've lived in the same general area now for twenty eight years and I'm still finding at least monthly some sweet quite little road to explore. When I tell the Mrs. I'm heading out for coffee she knows that could be a five hour event. Often she even goes along.    I like finding new rural routes used mainly by the locals that start nowhere in particular and end the same way. Many in the area of that type are narrow paved and twisty, hilly and run through field and timber. Often along creeks or wetlands. Unfarmable areas of great natural beauty.    After years of this type of exploration they start to fit together. One ending a mile or so from another and you start threading together a new path from a unfamiliar place to a new adventure. Sometimes to a little town of under five hundred that used to be something before the Interstate or some railroad or US highway bled the life out of it that has a small dinner with the greatest slice of pie you've eaten since grandma made her last. A little village museum or library or even a town square park with grand old oak, walnut and Osage orange trees to sit under while you sip you gas station coffee and chat up some locals.    Often they are full of stories about the main streets more interesting buildings and the who's who of the area. Sometimes some hidden attraction or unseen history. Our area is full of old coal mines.     A younger self used to do this going cross country by motorcycle. Only a general area as a destination with no time to get there and no time to be back. Sitting at days end in a 10 unit off the main highway motel under a Sycamore tree yacking with the owner or his one semipermanent guest while I adjusted valves or the chain. Always a wave and a shout "Hey there stranger"!  It's how I came by my love of old Brit iron. There is no such things as a ten minute gas stop when your on a Enfield or a vintage Triumph. Same being true of old cars.    If you take the time to really look I've found everywhere is someplace interesting. Illinois or West Virginia. Different and yet the same.    People are in a more relaxed mood and will talk about anything and everything and if they like you there may be a cupp'a or a lemonade and a sandwich in it. 😉
