Citroen C8 steel water pipe

Hello all, I have a Citroen C8 I have just replaced the whole engine due to previous injector non removal issues, however upon rebuild I now need some ancillaries, one being the steel water pipe that is positioned at the rear of the engine, Citroen have given me a 4 week delivery date, I need one sooner if anyone can help me, I have been on the part request sites but all come back with the same answer they would not split one from an engine because the engines are so sought after...
any help would be very much appreciated

Regards
Gary
