I've noticed that you don't even try to pack in that little bit of extra fuel.

No issues with mine.  I do however want a cap, I don't like the cap-less at all, I worry about dirt \ water getting in there.  I was spraying the truck off the other day and the water lifted the gas door open, that's all I need is a direct shot of water in there.   It's too easy for someone to mess with it also. 

 

Thoughts?

I bought a cover on eBay for 7 or 8 bucks. Think it’s just a glorified bearing buddy cover but whatever. They also sell locking ones at the auto parts store.

 

Supposedly there’s a drain in the spout that stops the water, but at least in the winter I like my little cover for some peace of mind.

That's perfect, thank you!  It does look like a bearing buddy cover exactly... but hey, if it works!

I remember seeing another thread on this with a bunch of different low cost options.

I actually found some good information on how the whole capless system works which makes me feel better.   I don't have the link still but it was right from GM.   Most systems have a spring loaded door with a rubber seal on it where the gas nozzle has to go through, so there is some force involved etc.  GM has 2 of these doors \ flaps not just one making sure dirt \ water doesn't get in there.   There is a gap between the outside and the actual flaps as well to allow dirt \ water to fall through  before it gets to those flaps and into the tank as well.  The system has been around for quite a while, I wasn't aware of any of this.   It's also nice because you don't have to worry about losing that cap or getting the dreaded engine code that shows when the cap isn't on!   I still kind of want something to cover it because i'm funny like that but it sounds like they really thought this through and you don't NEED one.  I would appreciate something that held the gas door closed instead of just a spring though, I want to keep the inside clean regardless.

I can't believe that a truck that can cost north of $80k CAD doesn't come with a locking gas cap.

I've had the same type of system since I purchased my 2014 Corvette, I was never really a fan of it but it's been flawless for almost 5 years now. The Corvette isn't out in the weather or slop that the truck is out in but I'd have to assume that they are pretty sure of themselves now that they are using it on the trucks.

The main reason I bought the cap is because after a winter car wash, I had some ice sitting on the first flapper. Undoubtably if me (or my old lady) just jammed a fuel nozzle into it, that ice would be pushed past both flappers and right into the tank.

 

A small amount of water may not hurt but really it’s no trouble for me to pull a rubber cap off. It’s not like I didn’t have to unscrew a gas cap on every other vehicle I’ve owned anyway.

I spend a lot of time down North Carolina's OBX. The wind blows the sand into every imaginable place when it's really ripping. I've seen a little pile of sand right on top of the trap door. I use the plastic 'bearing buddy 'cover shown by others when I'm down there.

Have a 2019 Silverado. Filled truck up 4 times now at 4 different stations in 2 different states. As gas tank fuel filler neck gets full gas nozzle shuts off and gas shoots out of filler neck all down the side of my new truck. If I did not jump out of the way it would be on me too. This is a brand new truck and has done this from day one. Plus gas all over the paint can’t be good for the clear coat.  It’s not the gas pump since it does it everywhere  and I have tried jamming the nozzle in as far as I can get it and tried pumping the gas very slow. Always same result, pump cuts off and then gas projectiles out of the filler neck.  Anyone else have this issue?  Thanks 

This just happened to me. New 2019 w/ 3k miles on her.  First time it’s happened, and I’ve had a 15 and an 18.  My 15/18 had the annoying fuel neck issue where the auto pump would cut off constantly, but not this.  Going to call dealer tomorrow about the fuel filter hose.  Has the fix held up?

Stitch :  I took mine to my dealer and they could not find anything wrong with the filler neck.  Next time I fueled up problem was magically gone so I don’t know what fixed it or if  just checking unclogged something ?

That's odd...my filler port is on the right side and the rubber plug for the DEF is on the left.  And mine is also a 6.2L.

Hopefully it's fixed, but I've got about 6 tanks in mine and this is the first time it happened.  Thinking back on it, the truck was autostopped and I don't think I ever turned off the ignition because I'm not used to the auto stop and didn't hear the engine.

 

Only X factor I can think of vs. the other tanks that filled fine, was yours completely off when you filled up?

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
