Hi,
In regards to the hose from the washer tank valve to the tire valve...
The hose to the tire IS correct for this car. Maybe not factory installed but correct. I had this setup in 1972 in my 65 but. It is different entirely from the newer style tire pressure system with the pressure hose going into the bottle cap.
I'll post again the quote from the Bentley Service Manual.......
Technical Bulletin z-13 states (paraphrased for length)
Part # 113 955 971 (the hose) can be added as an accessory and connected to the container from the spare tire.
The tire should be filled to 2.5 kg sq./cm (35 psi) and has a check valve that will not drain the tire below 1.3 kg sq./cm (18 psi)
The larger volume of air in the tire enables the container to be filled several times without having to check air pressure.
