Can some describe how the windshield washer works?
The shop manual does not show an exploded view, the owners manual says to pull and release.
Even with some force mine does not pull out, it does turn a little though.

Re: windshield washer
I assume you have a series 1 Fulvia. The original pump is a hand pump which consists of a spring loaded piston with rubber diafragm in a cilinder. You pull against the spring. When you release it the spring pushes the piston back. There should be valves in the plastic hoses. One at the end that goes into the container and one just before the nozzle.
If it does not move it is probably rusted and stuck. With luck the rust is outside the water part. You can try cleaning it. If the rust is inside the water containing part you best get another pump. If not rust will continue to block the nozzles.
It helps to put a fuel filter between pump and nozzles. You have to find filter that still lets water trough with the low pressure hand pump.

Re: windshield washer
I don't know if new ones are available. Most S1 owners change to an electric pump. I have been collecting their manual pumps for some years. Most are bad but the few good ones should keep me going for some time.
I have become attached to the good old hand pump in spite of all its draw backs. The low volume and low pressure require very small holes in the nozzles which are thus sensitive to blocking. Same low pressure makes the landing of the water on the windshield very much dependant on driving speed and wind. It is an art to aim the nozzles and operate the button in such a way that you get the water where you want it within a reasonable range of driving speeds.
I do sometimes feel a strong urge to reproduce those hand pumps in an all plastic version. So far I have been able to resist the urge as it is really a waste of resources.
In cases where I converted customers cars to electric I have used a high quality VDO pump.
See http://www.drivewire.com/make/cat/winds ... p/porsche/
The ones listed at about $ 52.
It has enough power to install a dense paper petrol filter between the pump and the nozzles. You may still want to install a wire mesh diesel filter between container and pump to protect the pump. Don't put a high resistance filter on the suction side of the pump.
VDO als has good quality chromed nozzles if you want larger nozzles but you may then also want to install a larger container. This is also available from VDO.
I noticed that some people mount the electrical pumps (and electronic ignitions) on the air tray. The tray is supposed to be mounted in rubbers. It is not a good electrical ground.
