Hi
I have just purchased a 90% complete series 1 and I have a question relating to the inlet manifold vacuum pipes. On the top of the manifold there are 2 take offs, where do these go? I have 1 going to the ecu but the other is left open.

Thanks
Phil

Thanks mate. I thought it may go there. I'm guessing it has a non return valve on it.

Series 1 cars did not have a non return valve IIRC. If going beyond stock boost it is probably a good idea to fit one .
