Headlight washer blanking?

Hey all,

The headlight washers on my 197 are annoying me so I plan to blank them, but have a few questions.

1. What blanking plates are available? Only ones I can find are from Mega Carbon.
2. Are there two individual washer pumps, one for headlights and one for windscreen? If not, how do people stop it leaking all over the place when disconnected?
3. Do they use 4mm diameter piping as well as the windscreen washers?

Any help would be appreciated!
