Just wondering if someone could help me, the two red vacuum lines that control the fuel pressure regulator and the IWE system that splice together into a 1/2 inch ell has come unhooked from the back of the engine. Where does it go? and how the heck do i get between the firewall and the engine to hook it back up? I have tried to find diagrams with no luck, cant even find a pic of the engine. Any help will be greatly appreciated.
