9k screenwash valves follow-up

I've just replaced the two valves that lurk underneath the wing liner. Only one was stuffed, but replaced both. The one rubber pipe was so short that it was a job to get it re-attached way down the side of the pump - in fact the rubber pipe itself was so short that it wouldn't reach as far as the retaining clip, and I didn't have any spare bits to lengthen it. Maybe Saab were using up all the odd bits. I guess it's been OK for 150K+ miles so why worry. Something that caught me out was that if you remove the rubber inspection plate from the plastic liner remember to put the darned thing back before you replace the liner. The little rubber bungs wouldn't push fully home despite thoroughly cleaning the plate and holes in the liner, and coating everything in WD40 then Vaseline. I pushed, shoved, grunted, and swore more than a little for about half an hour before ripping everything out again to replace the inspection cover. The worst thing about it was that I reckon I made the same mistake once before. Must be losing it...
