Electric power steering pump???

[Speed Demon]

Just about to finish fitting a saxo power steering pump to my cerbera as the woodruff key has snapped on the original, just having a bit of a problem!!! The saxo pump has The high pressure Outlet, The resevoir inlet so what the hell is the 3rd port for??? Anyone any ideas????

I have no idea where it is, but I know I have one of these on my car - if you're ever down south you can take a look.

I used mine as the return from the rack.

I have:

Pressure out (on the metal body of the pump)
That large port on the plastic section is the reservoir in.
The small port on the plastic section is the rack return.

I have blanked off the other port on the reservoir that is used in the original plumbing.
