“Gas Tank Cap for GM Capless Filler System (2018–2026) – Compatible with Chevy Silverado, GMC Sierra, Tahoe, Suburban, Yukon, Escalade, Plus More”

Fits like glove. I like that they keep dirt from potentially getting into the tank. I am not a fan of no gas caps on newer vehicles. Good quality, does not lock, push on and pull off. Would definitely recommend.

Cap fit perfectly

I work in a very dirty environment and this Cap is perfect. Fits tight and the cap hanger works great. Easy enough to get off when fueling and tight enough to stay on while driving. I would absolutely recommend this item.

The product works just fine. The issue is there is no lanyard. With my situation I was so used to not having a gas cap to begin with so I lost it in no time. I found that there is a Service bulletin with GM against the Silverado. They offer a GM cap at a little bit more but it has a lanyard that hooks up in the standard location. This product is fine if you are ok with no lanyard.

I have a 2020 GMC Sierra Sierra AT4 Crew Cab 6.2L, and like many others, the flap on my cap-less fuel tank has failed and is stuck open. This product fits perfectly and tightly over the fuel tank fill-tube to protect from any dirt and carwash water from getting into my fuel tank. I plan on using it even after I get the cap-less system fixed because this is better than the protection that the little flap offers. It is tight and it even comes with a little hanger that sticks on the inside of the fuel door so I can hang the cap there while I fuel. This is a great product and I will have it on my GMC as long as I own it.

Guess someone got a cheap 3-D printer to make cheap 3-D plastic caps that excel in flimsiness, horrible fit, what a total scam.... DO NOT BUY !!!!!

This thing fits like a glove...very impressed. Almost seemed too loose when I first put it onto the filler neck, but when I wiggled it and checked for effort to remove it, I realized that it really is perfect! No gap/wiggle room, yet easy to remove. Perfect for keeping dirt and water out of the opening of the "capless" fuel filler neck. The capless filler neck is nice, but very poorly executed as dirt, debris, and water can easily get into the top. My Acura also has a capless filler neck, but the fuel filler door has a shield built in that prevents anything from reaching the filler opening. Makes the GM execution look ridiculous!! If you have a GM truck with capless fuel filler neck, you NEED this cap.

I have a 2020 LT Silverado and this fits. I went to the dealership and the one they had fit, but it was too bulky and the door was slightly open. This one left the door flush. I need both hands to take it off but i figure that will hold well for rough roads.
