someone can definetly help me out with thi-possible fuel leak

Do you have a fuel pressure gauge? If so, how much pressure are you pushing? If not, how do you know it's not getting pressure? Have you pulled the fuel rails and primed it to see if it will shoot fuel? That may not be the safest nor cleanest way to tell, but that will tell if gas is getting up there.

I don't understand how you simply put a new quick disconnect on the fuel line. I also don't understand why you would hear an air leak from your fuel line? Perhaps it's from something else. Even still, if you did have an air leak, it would probably also leak fuel.

I want to help you, but it just doesn't make sense. This is the 84 in your sig right? I don't know anything about 84's, so that may explain some of my questions.
