Once all of that is out of the way you can swing the p/s pump and bracket up and get at the lines from the top. If you already to that point, yes those lines are tight but they will crack loose with enough muscle. If there is room slip another box wrench over the flare wrench to make it longer - there isnt a lot of room there though. Get a 18mm crowfoot and a long handled 3/8 ratchet if all else fails.
