Disco/RRC/3.9i Fuel Fittings

[CAPP0]

I'm in the process of converting my 90 to 3.9i V8, and rather daftly I didn't remove the fuel supply pipes from the donor Disco. On the fuel rail there's a screwed connection for the fuel input. I're measured it at M12 x 1.0 (slightly unusual but a recognised thread) but I cannot find any fittings anywhere. Tried Pirtek and they just shrugged their shoulders. What I need is an appropriate, preferably barbed, hose tail to screw onto that rail fitting. Does anyone know where I can get one? Tried the usual LR parts suspects but not turned anything up yet.

M12 x 1p is certainly possible.
M12 x 1.5p is more likely

I imagine you will have to start using adaptors though
