Yaris Windscreen Washer Pump Failure

[SW_Yaris_Owner]

The washer for the windscreen on my '54 Yaris D4D failed recently. Thanks to some excellent advice on this site I managed to uncover the washer reservoir to examine the pump. However, unlike others who have posted on this fault, my Yaris contains not one, but two pumps located in separate grommeted holes in the reservoir. Each pump is identical except for the electrical connectors which are colour-coded - red for the rear screen, blue for the windscreen.

I have temporarily re-piped the rear washer to the windscreen while I source a replacement pump. The pump is around 10.5 cm long by 3.5 cm diameter. It has a large inlet pipe and a small outlet pipe. It is marked with the polarity of the electrical terminals on the top and labelled "Textron". Has anyone had any luck in sourcing this component? I would expect to pay around £10 for this kind of thing at a motor factor, but I understand that Toyota spares tend to be wallet-drainers!
