Fuel lines for 4.2 Cerbera

[Shakinofftherust]

Does anyone have a diagram so I can see where the return line is - I have removed both fuel lines in the engine bay up to the steel bulkhead thread - I can see the metal end for the inward fuel line in the rear arch - but the return line disappears into the inner frame and is a rubber hose - where does the metal pipe start and end for the return - is that just a much shorter metal pipe? Seems daft?
I have removed all of the pipework in the rear arch - filter etc - and I'm under the car -
Just don't have visibility of that return pipe - and don't want to take the gearbox out.

Cheers
Justin

Rear wheel arch, into the cabin, under the helmet holder and the pipes run down the top of the center console
