Any place that makes hydraulic hoses should have the low pressure return line. Buying the steel wire reinforced 5000PSI rated stuff is overkill and you may injure your self on the wires sticking out on the ends.
Another way to do it right would include a PVC grade emissions hose from a professional Auto Parts store like NAPA or Car Quest. THEE Extra Sharp Pencil Bean Counters who buy for most of the discount Auto Parts stores will not stock it.
Also braided Tygon tubing from a Hardware Store or Home Depot or Lowe's. This option is cheap and will last up to five years before it gets stiff, shrinks and slides off the barbed fittings, so use clamps.

I used a 90 degree 3/4" hose barb to make the turn from the valve cover to the middle of the CCV body.

CCV body is a 1-1/2" T with bushing adapters and 3/4" hose barbs. Drain is 1/2" at bottom, with a ball valve.

The intake hose has a flexible support to keep it from collapsing.

Here is my link, finally got it done: http://picasaweb.google.com/warp2diesel ... #slideshow

Next I will connect the drain to send the oil back to the pan.
