Certainly willing to give it a go as i can see those still on sale new OEM for a tenner. Same size connection into the washer jet?You could back date the car and fit a "Y" connector instead.
yup thats the issue - I'm not convinced the connection into the actual jet is the same. If you look at the picture above it looks bigger than the pipe size connectors which are 4mmCould not say 100% but both connectors use the same size corrugated pipe.
