Miata Turbo Forum - Boost cars, acquire cats. - Simple question about BEGi-S4 installation

Question is pretty basic. I'm mostly done with the disassembly part of the turbo installation with just a little bit to go, but I can't envision the coolant reroute very well and I could use a tip from anyone familiar with the process at this point.

Regarding this quote from page 6 of the installation guide: http://www.bellengineering.net/templ...ns_Series4.pdf The test says to pull off the cast aluminum neck. Do I pull it off from the rubber part, or pull it off from where it is anchored on the engine? Does it go back there later?

Quote:

Removing the Water By-pass:
The water by-pass tube (located beneath the exhaust manifold, and anchored to one of the manifold/head studs) must
be removed. Remove the power steering pump and it’s mount. Pull off the cast aluminum ‘neck’ that originally held
onto the lower radiator hose. Refer to picture # 10 . The PWS pump will re-install later with a new water by-pass
tube.

You can look at picture 10 on the pdf to see what I'm talking about.
