leaks around injectors

[David Dodge]

I have noticed slight fuel leaks around some of my injectors recently. Do these leaks usually come from the braided fuel hose on the leak-off connections or from the injectors themselves needing tightened up. If so do they need to be torqued?

Or is there something else around that general area that needs attention???

Is the braided fuel line common at auto parts stores or should I order it from fastlane and wait.

Thanks from a humble neophyte!
