Im currently in the process of replacing the Evap canister for my 2007 tahoe and am currently stuck trying to get the hoses off. I can feel the button depressing in when i press it but when i then pull theres zero movement. Any tip or tricks to getting these things off would be appreciated.

On the larger one push the connector toward the canister and use two small pocket screwdrivers or the like to move the latches outward, see the straight lines below in the pic. It helps to push the connector toward the canister and twist it back and forth a little before pulling it off.

For the smaller connector, push the connector toward the canister to take the pressure off, twist it back and forth to help break the seal, then squeeze the blue lever (red rectangle) on both sides of the connector and pull it off.

This response was on point. Did you have that pic shotgunned ready to go? lol

fna sorry for the French. I just went through this myself, separate thread of my own. I broke all of them haha PITA cause I had to remove tank, evap lines and rebuilt it all with new ends.

Honestly, GM put JUNK there. Probably all the other manufacturers do the same thing. If I had more time I'd rebuilt it right with better fittings and adapt the ends on the evap canister.

Blue one isn't too bad. The white one, you have to take a screwdriver or something and slide open those tangs so they'll pass over the raised edge on the male side. Might not hurt to spray with some Armor All to soften up the plastic a tad.

I went to junkyard to find parts to replace my broken quick connects. All the trucks had same issue. Seems this isn't uncommon. Designed to not be rebuilt easily.

I tried to do mine, it put me in the hospital! LOL Each connector with a different way of removing them is crazy to me.

If I ever have to touch that stuff again, it's all going into the trash and the tune will turn it all off so no codes.

I changed mine no problem, just like noted above just pushed them forward first, press and release.
unlike the heater hose T's those can go to hell
You have natural talent Wes! I studied the instructions and still couldn't figure it out! LOL

A couple of cheeseburgers and a gallon or two of mountain dew and my helpers knocked it out for me!

You live in the ideal climate for anything car-related not aging like shIIIIIt.
no rust but the heat kills other stuff makes plastic brittle and rubber deteriorate eventually unless you are fortunet enough to have a garage to park in
overall they last a lot longer here though.

Yeah, when I lived in Oakland I saw so many older cars, just regular cars.... nothing fancy, but they had zero rust on them. If they were in NH, they would have been Thanos-snapped back into minerals 100 years ago.

ya if you go to the junkyard here the worst the very oldest vehicles will have is maybe some light surface rust from exposure to air depending on if the paint or undercoating was still decent or not
anything greasey is pretty much like new underneath the grease
if you see something with rusty holes or eaten away then it didn't come from here.

I was have a hard time filling my gas tank so I think the previous owner was over filling the tank at fill ups. My 2011 was tuff to do on my back. I use PB blaster which made it slippery. The o-rings tend to melt on the plastic but I worked them back and forth and they came off. I would NOT want to do this again on my back because you don't have the leverage.

When you do get them off can you tell me if there is an o-ring inside each of them? I ask because I vacuumed (not advisable) all the carbon pellets out of the hoses and get an evap error message. Everything in the Evaporator system was replaced except the hoses. I’m wondering if I may have sucked an o-ring out of the hose with the vacuum.

Yes there are seals / o-rings inside each of the hoses. I used a mirror and made sure they were not damaged. It would be possible to accidentally vacuum them up by mistake.

Back again after another attempt and I have to say thanks Fless for the diagram for the big hose as I have now gotten two of those blasted hoses off. However, even after trying what you suggested for the blue-clipped hose I still have yet to be able to get it to come off. We are now trying to use a pair of lock pliers to hold the piece down while we pull(check video) but it's not budging in the slightest. Have zero clue as to what we're doing wrong at this point so any suggestions are welcome.
