On other cars i like to jack the front up , plumb into a return and swap out the fliud that way.......................

ls there a favoured way off doing this on a V12 HE?

Thankyouverymuch AOI

 

I have just pulled the steering rack out of mine, and I used a 6mm pneumatic air line / tube to suck out the fluid and there was not a lot left when I undid the hoses connected to the rack.
Basically what was left in the hoses.
Other may have a proper method.

 

Yep.

A hose, a syringe, suck it out of the pump filler cap (under the B bank top radiator hose), refill, do it again in a weeks time, all sorted.

 

Many thanks Gents, way easier than taking stuff off.
