I'm replacing the head gaskets on my 96 blazer. I pulled off the exhaust manifold and removed all the bolts from the header on the driver side. When I tried to pull the header off I discovered that someone was attached to the back of it. I cant see it very well but I can tell there is a small bolt attaching a clip holding some fuel lines. I can't get a 14 mm wrench or socket back there to remove it. Any ideas? Thanks,
