Orifice Tube O-Ring?

[swaggerwagon]

When I replaced my orifice tube last week, I'm realizing now I don't think I replaced the O-Ring on the line that you have to disconnect to pull the tube out.

Does anyone know a P/N or am I going crazy over here?
I found this on ECS: 8E0260749

However, I cannot for the life of me find it on the GAP diagrams. ETKA would be a lifesaver

it didnt come with a new o-ring already installed?

Not the O-Ring on the tube, the O-Ring on the AC line you have to open up

Did some more research. Found an online ETKA website

Can confirm ECS P/N is right one!
