Steeroids Owners?
Jim Shea stated all of the earlier pumps were standard sizes and the 80-82 were metric. All hoses were set-up with large and small fittings on either end so you could not accidentally reverse the installation on the assembly floor. Outlets were always 5/8 (16mm later) and inlets were 11/16 (18mm later) so they were idiot proofed.
If you go to the Hydratech Braking Systems website, Accesories page section, you will get info on all of these fittings described with year of car-pump, since the hydraboost is using these lines also.
Hope this helps.
Also do a search for Jim Shea user and "steering hose" in text for more background.
