drive shaft driven pump at diff., NASCAR

[fiatboy]

I'm building a Monogram 1/24 NASCAR kit.  I has what must be a pump, oil pump, driven by the driveshaft at the differential.  I would like to know how to plumb this.  Is it the engine oil?  The sump is right by the rear suspension and diff.  I will use, I guess, some flexible rubber fuel line.  I suppose it just goes right up through the floor.  What should I search for in my browser?  Thanks (again).

It pumps the rear end oil through a cooler.

One line out of the diff to the pump, a line from the pump to a cooler, a line from the cooler back to the diff.

Google image search "nascar differential cooler" for lotsa pix.
