Removing turbo oil retun pipe?

Right as the title says, I have a new turbo oil return pipe, I have replaced the top gasket in the past so no dramas.

But how do you remove the end with the union that connects to the adaptor then the block? Its 26mm but I,ll be buggered if I can get it off, thinking either stubby spanner or maybe a crows foot (if I can find one that size)

So how have you lot done it? dinna want to force it and strip the threads, I have been known to be heavy handed in the past

When I tool mine off I ended up removing the adapter and pipe as unit (after disconnecting turbo end) and stripped them on the bench. Left the pipe / adapter loose when re-assembling, tightened adapter then pipe union (after reattaching to turbo)
