Didn't watch the video, But I've found WD-40 & compressed air to work very well on stubborn EVAP & quick connect fuel fittings.
Fine silt/dirt gets packed in the release mechanism.

That dude needs to read service info if he doesn't know what he is doing. Good grief, if you can't remove a quick disconnect, just slowly back away from the engine.
I recently posted about this on a '19 KL airbox. Someone had tried to "pick" it out and damaged the clip in some way I didn't care to investigate further.
If you can see in there you can run a pick inside and release the mechanism. Not much different than releasing electrical connectors by lifting the tabs with a pick.

Some of those chevy coolant fittings have to come off in pieces after 20 years. The only durable part of those things is how well they get stuck on the heater core with their big rubber seals, and when you pull on them they just finish breaking
Most quick connects are fine

What’s getting lost in translation is these connectors release by pushing in the button, not fooling around with picks. It’s just that the fitting needs to be pushed in to relax any loading against the mechanism, something simple that some shade tree mechanics miss.
Note to self: It is time to clean my picks.
