Thanks for all the advice guys.
I sorted a valve....I had some spare washer jets & tubing from my old Citroen & there was a NRV in the tubing...so I fitted that & now the washers work straight away
See... that's a good excuse for not throwing any junk out....you never know when you will need it.
I read on the web of people using those on their kit cars so one of those would have been an option.
Yeah I removed the old one but there is nothing in it...nothing at all, I can see straight through it.
