HI people. Am doing a bit of work to my car at the moment and am tidying up some bits in the bay when I came across this. I have seen it before but didnt pay much attention to it. Any ideas what it is? I am running a late spec (92) saph, greentop lambda model. This unit seems to be incorporated into a breather line, and anoter line seems to run towards the back of the car, near the petrol lines. Any help would be much appreciated. If it is not needeed I would rather get rid of it.
