Can you take a picture of the pipes that go nowhere?
It will help identify and likely speed up the process of determining where the pipe should go.

The pipe in the top picture that is marked "Vacuum line" this is blanked off on my normally aspirated 2.0 with a 34 DATR. On my car there is a very small brass T section that comes off the inlet manifold.
Re: The top picture... Is your brake servo connected??
In the lower picture the larger bore connection with no pipe on it I think should be the crank breather and that used to have a pipe running up to the underside of the stock air filter housing.

Matt,
I think the pipe in the top picture that he says has pressure could well be the crank breather hose. Unless you got had a really good look in you might well think that comes from the inlet.

It does look like the crank breather just by the shape of the pipe and the marks from the hose clip, it looks like its the right routing to fit onto the underside of the air filter housing.
The pipe-less connections are throwing me a bit.
We'll get there slowly but surely :~)

Looking at where the photo is taken from (past the dizzy) it's not the fuel pump is it? |

So the question is: has the mechanical fuel pump been replaced with an electric pump?

Has the car been converted from automatic to manual at some point? The automatic cars have a vacuum valve controlling the idling speed and it could be that some of these lines were not connected when the car was converted? Top picture, both pipes should connect to the air filter. The bigger pipe is the crankcase breather and the second pipe is the EGR (exhaust gas recirculation) valve pipe ( I think  ) Has your car been fitted with a K&N (or similar) air filter? A lot of people don't know what to do with these pipes once they change the standard air filter. The two unconnected pipes on the manifold are meant to connect to water pipes for manifold heating? This is the case with automatic cars but might not be for manuals. |

and the second pipe is the EGR (exhaust gas recirculation) valve pipe ( I think ) On second (and more careful) look, no it isn't! The EGR pipe is shown above it and seems connected (to the carburettor end at least). The small unconnected pipe is just a vacuum pipe which would connect to the idling adjustment valve for an automatic car. |

Yes it has a electrical fuel pump I was told by the previous owner. so these cars originally came with mechanical fuel pumps? |

I dont think think this car was a auto I believe its always been a manual. and the fuel filter has been replaced it has a 34datr its weird because its a auto choke but it also has a manual choke on it. |

As standard it would have had a mechanical pump just under the inlet manifold.
It's possible that you might have a DATR with a manual choke conversion fitted. There were kits to do this or it could have been done with parts from a DMTR.
