Not liking the capless gas cap system on 2017s

[SouthernSilveradoGuy85]

For me, it's not so much the fuel stealing, it's the idiot that comes by fit no reason and puts something in there besides free fuel... Say you have your favorite teams sticker on your window, some rival fan decides he's going to be a hero, and add something to your fuel. You will not know until it's too late...

 

 

Good point.

 

 

That's the reason I had a locking door (not cap) on my old '98 and my '14. A locking cap is cheap and most if not all doesn't seal as good and usually throws a code. The only reason I worried was because a few years ago kids would mess with people's vehicles. One time someone shot BBs at a handful of cars trying to shot on windows. Luckily they missed my '98 and hit just below the window and left a dimple. Then someone went and slashed a tire on 3 or 4 trucks including mine. Now a days there doesn't seem to be a problem, but you never know.

I miss having my gas cap to hold the service station nozzle going while I clean my windows, etc. Now without it... I find myself going more to the full service station than the cardlock just so I'm not standing there swearing at my stupid truck for not having a gas cap lol

I know most of these trucks rarely see anything but the mall. But in WY, CO, IA, etc. there are lots of dirt/gravel roads and that dust gets into everything. What's the fix?

I ran a Dodge rental on some of that nastiest BLM roads in Idaho, everytime I opened the fuel door, it was clean.

 

If they design it right, should be a non-issue.

Well, since Ford has been out with no fuel cap systems for a while, that might explain why Ford isn't a market leader in Iowa. They never were top dog in Iowa, but they effectively made sure they never would be. And living on gravel roads, you are correct, dust gets into everything. About the only thing dust doesn't get into over time is a container that has never been opened. It is one of several reasons why I don't follow the OLM for my oil changes. And the closest some of the folks who come up with this stuff came to rural living was taking their kids to a petting zoo to pet a goat.

Exactly why GM needs to come up with a locking fuel cap for the 2017 Silverado / Sierra configurations. Anybody find one that works? I bought a chrome locking fuel door and it was advertised as fitting the 2017 but it only fits a 2014 and 2015. The mounting holes don't line up with the existing rubber stops that are used to secure the door to the truck.... Not happy....

I use plastic water bottle to hold pump handle when filling up. No issues

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.

 

Not sure what can be done, but it is the way everything is going.

I have this on my Denali, my Corvette and now on my wife's Caddy XT5......hope it doesn't end up being a problem!

I am currently on the process of tracking down the correct part numbers so I can convert my truck to a non-capless system. When I get it figured out, I'll post up...

Have this on my 2017 2500hd, don't particularly like it. Why on earth do we need this? Who is so lazy that taking off the gas cap is a problem? Stupid, stupid, stupid. If Ford makes a cake shipped car, wtf, GM has to fallow? Truly stupid.

Keep me posted, I want to do the same to my truck!

Where I’m from folks hate and it ain’t nothing to sweeten up ur tank. I’m very noid with this capless system

[Mileguru]

This won't help with any locking issues, but there is a plastic cap that goes over the capless circle/hole/structure to keep it clean. Search "WATER DUST GAS CAP COVER 2017 2018 CHEVROLET SILVERADO CAPLESS FUEL FILL" on ebay. I'm going to see if Home Depot has a basic plastic cap like this that will fit.

 

[Thomcat]

It's a shame that owners have to resort to this.....it wasn't a redesign it was a too lazy and too cheap kludge on an existing chassis. Glad they didn't do me that favor of a capless system on my '16. Likely more for Chevy than owners so they don't have to reset engine codes or deal with complaints related to a loose or missing gas cap.

 

Doesn't mean they can't design it properly from the ground up. My '18 Traverse has a properly designed capless system with a baffle on the back of the fuel door that fits neatly into a recess protecting the cap area from water dirt and dust plus an interlock to warn if the door is open while driving away. Bottom of the filling hole is tapered outwards so pilled liquids or a driving rain while the fuel door is open will not remain up against the closed door and the hinge area is encapsulated instead of the Silverado's hinge which opens directly into a hole in the inner fender open directly to the ground. Outer body covered with road salt and road crap, but the fuel filler area remains clean as a whistle.

 

When using that 25 cent PCV tubing cap it might be a good idea to inform the wife before she fills up or warn a filling station attendant in States where you can't pump your own. Failing to do so, a well placed blow from an unleaded fuel nozzle might be enough to force it into the pipe and really screw up the spring loaded doors.
