Filler neck conversation

I have a 2017 Silverado with the capless fuel filler, I have had nothing but issues with it and am wondering if there is any way to convert my filler neck assembly from the capless style to one with a cap.

 I know the 2014-16 models came with a capped system and I'm wondering if the filler neck configuration is the same and 100 percent interchangable.

The filler neck literally fills with water and freezes solid. Making it impossible to get fuel unless I stand in my driveway with a hair dryer defrosting it. It's bad enough I gotta do that when it's -45, but on a brand new truck I shouldn't have too at all 

 

This issue is also making me believe there would be water in my tank. I understand there is a drain hole on the filler neck but if waters getting caught and freezing clearly it's not draining

Have you at least tried one of these make shift caps in this thread for now till you can swap to a cap system? Might be better than nothing for now and they are all fairly cheap minus the worthless locking GM one.

I have tried the 2.44" Curt bearing cap but even that froze to the outside of the filler neck and had to be cut open in order to purchase gas. 

 Haven't tried the gm one because the dealership said it's non-warrentable and wanted me to pay for it.

I would’nt bother with the GM one from what I’ve read on here anyway. Just didn’t know if you had seen that thread or not. Apparently you had.

Clearly something isn't working properly. Dealership doesn't want to seem to do anything to help me. So any suggestions are very much appreciated, thank you.

Wow.. that is a strange issue. Never heard of that one before.

Bring it to the dealer when it’s frozen demand a fix.. or call GM directly.

Putting a cover on it is just a band aid.

They need to make it right.

 

I bought the OEM cap/cover on eBay for around $15... I found it to be a pain to put on and remove as it has a stupid plastic neck grip that’s operated by a key. The cap is somewhere in my cab since I removed it after 2 fill ups.

 

I posted a pic of it in the above link (post #2)

Then I mentioned it’s a pain in the ass

Lol!

Issue with bringing it there when it's frozen is I work 10-12 hours out of town in northern Canada. I have no choice but to fix the issue myself.

 

And that's my point exactly, I've bought a handful of new trucks/cars from this dealership and they don't even want to give me a 30 dollar part, Ridiculous.

Ah, never would have thought of that. I'll steal one from work and give it a shot. Although I feel like it's going to freeze on just like the bearing cap as it's the same idea

I have a PVC end cap, can’t imagine it freezing on there...it fits snug and easy to paint to a color close if you care about that. $1.98 at Lowe’s

my issue with capless filler is large evap leak code/ check engine light/ cannot use remote start if check engine light is on

Change out the capless filler vlave.
When I first bought my truck that is what the dealer did first as it was bad.
Not sure of the cost but it didn't seem to take long for the dealer to replace it.
Quite frankly, I find it more convenient than I expected.
When I fill up the BMW, I gotta unscrew the cap, fill it up, then, screw the cap back in (occasionally, it also needs replaced).
On my truck, it's fill up and go. :D

      I could be interested if they axed cylinder deactivation and at least have a button for stop start. I’m sure the HP numbers will be higher. I would want a longer warranty to help build confidence. I’m a less is more guy as I get older. A V-8 work truck model would be my choice. I know a few outfitters for custom additions I prefer.

      2027 GMC Sierra: Official Discussion

      By Zane · Posted

      It's official. GMC pulled the covers off the next-gen 2027 Sierra 1500, and we got the first official look. Full breakdown here: https://www.gm-trucks.com/next-gen-2027-gmc-sierra-1500-v8-trim-changes/   The quick hits: SLE and SLT are dead. The new core retail trim is just called "Elevation". Two new V8s, a 5.7L and a 6.6L built with high-performance Corvette architecture roots. No horsepower or torque numbers yet. The 2.7 TurboMax finally ditches the old gearbox and gets the 10-speed automatic. AT4X moves to larger standard 35-inch tires with front and rear e-lockers, Multimatic DSSV dampers, and heavy-duty Jounce Control Dampers. Over 60 inches of combined display on Denali Ultimate and AT4X, complete with a motorized articulating center screen and an adaptive passenger screen. Seven simplified trims across the entire model line to clean up ordering confusion.   So let's get into it: New 5.7L and 6.6L gas V8s with custom active exhaust tuning and a Corvette connection. Is this the exact engine lineup half-ton traditionalists have been begging for? Purging the iconic SLE and SLT names after all these years to lean entirely on Elevation as the high-volume core. Bold move, or a mistake? That motorized articulating 16.3-inch screen that slides up to reveal a hidden dashboard vault. Awesome mechanical theater, or does it make you nervous about long-term durability? Physically lowering the headlamps in the front fascia to improve road courtesy and stop blinding oncoming traffic. Smart real-world engineering, or does it hurt the truck's aggressive stance? What trim are you putting your name down for on day one? Drop your first impressions below.

      My overnight hospital stay turned into five.  I developed a post operative fever and an erratic  heart rate.  A blood clot in the lungs was the culprit.  This is apparently a common post surgical complication and easily remedied.   I was the youngest in a four bed ward and a Doctor with a Geriatric specialization was in charge of my care.  All of the nurses were good and some were outstanding at dealing with old people.  It was very evident that my age triggered a different level of care!  My advice to any senior going for a hospital stay is to have a trusted family member advocate visible.  If not, you will still be well cared for, but you may discover that your voice  isn't as strong as it once was!
