7.3 Fuel line replacement

[Kps2389]

For the guys out there who have replaced the passenger side fuel line from the bowl to the head, how do you loosen the fitting on the head? I removed the intercooler tube to get back there and have tried about every way and can't get a wrench on there to get it loose. Am I missing something? Do I have to remove the turbo or downpipe? Any help appreciated.
