A few questions (regarding lamda plug and pipe work)

[Hpi_matrix]

What does this pipe do (the one between the cam cover and cambelt cover)? And wheres it meant to go where it leads down the front of the engine?



How do I disconnect the fuel lines? The spin round and look like they should unclip somehow, but they feel fragile and I dont want to brake them! Also which is the inlet and which is return?



Will any lamda sensor fit my car? I currently have a MK1 VTS one, but the colours on the wires dont match up.

1) goes to carbon cannister in wing(does crap all) for emissions/something about fuel evaporation.
2)should be a button(like a different colour) push in and pull
3) they all fit irc

Which is the return on the fuel lines?
