I have a 1998 GMC Sierra, and my hard fuel lines on top of my intake manifold are leaking, I’ve read that they’re supposed to have o-rings on them, I can’t find anywhere an o ring would sit. I’m wondering what it should look like.

Can you upload a picture of what part is leaking? I assume it is the fuel lines going into the fuel injector spider which is common. Here is how to replace the O rings on the fuel line in the images below.
