Leaking BX FEL quick connect line

[Tdog]

I have [finally] found a slow hydraulic leak - - its from a FEL quick connect line. I have raplaced a hydraulic line on my BH before, so this should not be hard, but it is. I have attached a couple of photos showing the line I need to replace. Problem is, I cannot get wrenches on it to hold the base & break the nut loose. I am not even sure I have the right size wrenches.
Does anyone have any suggestions as to how to get wrenches into on these nuts? Do you know what size?

I sure hate to send it in to the dealer for what should be a task so simple that even I can do it.

Thanks much.

Jack

you may need the correct size box wrenches, rather than adjustables, but it should loosen without too much force.
You are trying to loosen the two silver 'nuts', correct??

The brass colored 'nut' has a fitting end installed on it (the top silver 'nut') which will take some effort on the bench to break- if you even can.

You may need the hose plus the coupling end.

I can look up part numbers for both later- not at my present location.
