On mine, there's a pipe that comes out of the reservoir and rather than going to the cooler (u-bend thing), it goes the complete different direction and goes straight to the rack (I think).
EDIT:
So, looking at the picture you posted, 39 comes out of the reservoir, goes into 38 which then goes direct into 22. I didn't do it mind, it was done by a previous owner. I think they just used 23 but turned it round to feed straight into 22.
Hope that helps
