Steve,
If all you need to do is splice it, go to a local hobby store and some fuel line tubing. You need to be sure not to have more than 1-2 inch 'gap' between the spliced ends as the splicing peice will col apse. I did this repair at a few locations on my 240. If you need a long peice of the tubing you will need something stiff enough.

I bought some from the MB dealer here. It is not color coded just all white. To color code it I used red and green sharpie pens.
