I bought a set of flare nut socket "crows foot" In both sae and metric and I think I may have actually used on that exact problem.
Combined with my triple jointed "Dr Seuss" ratchet (that literally goes around corners).
Holy crap they have it again. I'm going to get a spare I've been looking for almost two years to find this crazy thing.

This one beats the expensive brands hands down because the first swivel is at the head not inches from the head.
