2017 yukon xl fuel injector type

[Gmfm]

I’ll be replacing my injectors and high flow fuel pump soon. Im having trouble locating the correct injector part number. I keep finding injectors that say “use with injectors marked (insert number here)” and I am trying to figure what injector I need without removing them first. I understand that there’s a non reusable fuel line(s). Is there one or two of these that I need to order as well?

Nevermind I see there’s a nhtsa special coverage adjustment for this. I’ll try to get a dealer to pay for it.
