Its the cylinder 1 injector. I had to move the fuel return line going to the filter head to get better access to it. Plus there is something else installed on this injector between the hardline and the cap that the other seven didnt have. I just tried to loosen it again and its still trying to twist the hard line. Sprayed it again and will try again tomorrow I guess.
Rob-
The #1 injector has a timing adaptor installed between the hardline nut and the injector. You'll need an extra 5/8 wrench on the adaptor to hold it still so you can break the injector line loose from the adaptor. Once that is loose, you can then remove the adaptor from the injector to gain access to the return fitting.
Hope this helps.
