The all-new 2019 Blazer delivers attention-grabbing design, superb functionality, and a bevy of seamlessly-integrated technologies. One of these technologies is capless fuel fill, which removes the traditional gas cap in hopes of making fueling the new Chevy crossover SUV more convenient.
How It Works
The capless fuel system on the 2019 Blazer removes the traditional gas cap, and replaces it with two flaps (sometimes referred to as “doors”).
All that’s needed to fuel the new Blazer is for the owner to open the fuel door on the outside of the vehicle, insert the nozzle into the fuel chamber and begin fueling. Inserting the nozzle into the chamber automatically pushes aside the two flaps/doors, in much the same way that a one-way valve works in various plumbing applications.
Once finished fueling, simply remove the nozzle and close the fuel door, with no unscrewing the gas cap, fumbling to hang it, or replacing it.
Improving An Existing Technology
Capless fueling has been around for quite some time now, but GM’s implementation differs from those used by other automakers, since GM’s system features two flaps or “doors” inside the filler tube, with rubber seals around the edges of the flaps ensuring that the system remains air-tight and locks the fuel in.
Meanwhile, capless fuel fill systems used by other automakers only have one such door, making them prone to fuel leaks. What’s more, GM’s system has no internal drain, which eliminates the potential of fuel dripping from the filler chamber, though we should note that things might get messy if one were to over-fuel the vehicle, which is rather difficult to do with today’s sensor-equipped pumps.
Benefits & Advantages
Besides the obvious benefit of greater convenience as a result of not having to remove the fuel cap, capless fuel fill has a host of secondary advantages for both the car and the driver.
Driver benefits include keeping the driver’s hands clean and free of dirt and fuel, while also eliminating the risk of leaving the gas station with a dangling or missing gas gap.
Car benefits consist of keeping the vehicle’s paint clean and free of fuel and scratches caused by a swinging gas cap and enabling a smaller fuel door, as it no longer needs to accommodate a hand, in turn making the gas door less noticeable on the Blazer’s exterior.
Additionally, capless fuel fill also has the ability to keep the Blazer running smoothly. This benefit typically raises some questions, so here’s a brief clarification: since fuel systems must be fully sealed, a loose cap can trigger a “check engine” light, thereby leading to a service visit. A capless system simply eliminates the possibility of a loose gas cap. It’s a small detail, but one that separates a good vehicle from a great one.
We asked GM about the reliability of the system, and were told that the “two doors (flaps) in the filler tube are designed to assure the system will remain air-tight through years of ownership.”
Second Chevy CUVÂ To Adopt Capless Fuel Fill
The 2019 Blazer is the second Chevrolet crossover to use capless fuel fill, with the second-gen Traverse being the first.

My Acadia and Canyon have had this system since 17.
The only thing that sucks is now in the winter you have to just stand there waiting for the receipt now when in the past you killed time with the cap.
I guess you could slowly and very carefully close the little door, inspecting it for dust and debris as you close it.
Maybe the next innovation in fueling could resemble something like this.

Can you imagine, never even needing to pull off the highway to fill up. Having those fuel trucks rolling down the interstate pumping your gas as you go. I never realized stopping to fill up was such a waist of time, the accrued cost to America must be enormous.
Buy a Chevy Bolt EV and you will NEVER visit a gas station to fill up!!!
Scott, you could try this!

Ford’s had this for some time… As a side note, that white Blazer in the top picture is undoubtedly the best looking CUV I think I’ve ever seen. Man that looks good.
GM vehicles have had this as well “for a long time”.
But more importantly, some Ford models that have had capless fuel fill use a single valve/door… which is why Ford owners often complain of small amounts of fuel coming out of the tank… GM’s system is set up differently.
Seeing the picture of the 2019 Chevrolet Blazer in all White for the first time, the Blazer looks almost like a sports car as it sits low to the ground and appears if it had spent a bit of time in the wind tunnel to fine tune it’s shape.
We’ve got pictures galore of the white one (the Premier model) right here:

Cadillac will also offer capless fuel fill in the new XT4:

90% of GM’s current vehicles have this…. useless post
All Corvettes have had this feature since 2014.
People are so damn spoiled…fumbling with the cap. The cap keeps water and debris out. Once you have to be towed in because it quits a cap would be priceless. I have a Ram diesel without a cap and the first thing I did was go to eBay and buy an aluminum one with an o-ring to keep stuff out.
Is it just me or does this Blazer look an awful lot like a Lexus RX350?
I want evidence of all the myriads of reports of how terrible this feature is and all of peoples problem
I have a 2012 Ford Fusion with capless fill . Works perfectly , no fuel spill at all . Must be one of the lucky ones !
