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 

Having that very issue with cutting off when tank is very low. Just filled up and it kept cutting off up to 12 gallons into tank. I have the same issue with my 08 Silverado.

has something to do with the evap canister. This should not be going on with new trucks however. Very disappointed

GM sells a locking gas cover for these trucks. It was about $50 in Canada. It is a little cheesy and could be pried off easily but it keeps the dirt out which is all I wanted. Also up here it was shown for 2019’s but not 2021’s. it does fit though.

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.

 

Anyone know how to remove that whole assembly?  Mine has 4 plastic locking tabs on the back of the assembly but I have no way of knowing how to get to them.  Just pry around the perimeter between the seal and the car frame?

To answer my own question as I have changed it out successfully.  There are 4 locking tabs on the backside of the assy.  2 on top and 2 on the bottom.  I could not gain access to the top 2 so I reached the bottom 2 by reaching up from beneath, unlocked the tabs and pushed out on the assy.  I pulled the bottom of the assembly out far enough to cut the plastic with a hacksaw enough to break the assy in half to remove it.  I fit the rubber seal around the fuel filler tube as I put the new one in

Well took my truck,to the dealer today. They removed the fuel filler hose and checked for any blockage.  Finding none they put it back together.  Filled up and no fuel spilling out and the gas nozzle  cut off as it should when the feud reached the filler neck.

 

Hope it will last!  No more fuel on my truck and all over the ground. Bit puzzled why taking the hose off and putting it back on without doing anything fixed it? 

 

Any ideas? 

Fuel filler has 2 hoses internal and external its possible the internal one wasn't positioned correctly pulling it appart and putting it back together repositioned the i ternal hose correctly.
