So the mechanic said he's never seen this before(leave it to my LEMON). But there is a pinhole leak in the plastic elbow connector that comes from the gas tank to the ? manifold? Trying to find out if I have to replace the whole fuel line or if GM makes some sort of repair kit for this.

 

I believe there is a repair kit made by Dorman (if I'm right you can walk into any parts store, they have a Dorman HELP! section and you can find it there).

 

Thank you so much!
