Hi there,
I used one of these so I could do the bleed by myself.

3L Brake Bleeder Clutch System Fluid Power Bleeder Tool Kit with E20 Adapter
This particular kit with the E20 adapter did not fit onto my brake reservoir - if someone can share where such an adapter could be found that would be great (I bought a whole kit of them and had to cobble together bits to get the correct fit but an off the shelf item would be better.

11mm spanner required for the bleed nut.
Regards,
Paul
