[Closed] Shimano banjos - help please

I've got an old set of Deore M556 disc brakes and I've just sliced the rear hose open on a rock. It seems the original hose kit is out of stock everywhere, or else silly money. Can anyone tell me if this Saint hose will fit?

The banjo looks the same but I can't be sure. I can re-use the bolt and seals as long as the banjo itself is compatible.

Or does anyone have another cheap solution? I'd like to fix them if I can but new Deore brakes are so cheap that it's tempting just to replace them.
