metering head replacement

i need a metering head for a 1.6 petrol injection, how much am i looking at and have you got one? the fuel filler neck rot has got thru to there and the injectors.

alternitively is it possible to clean it out rather than replace it or is that the only option?

They range from ?10 to ?60 mate from what I've seen.  Post a wanted ad, check with funk-star, big boys toys, crazyquiff and e-bay.
