Hope you will see tham now…

Theres three possible things that could be there, the first is the vacuum advance for the distributor but this should be on the back of the throttle body I thing.  the next is a vacuum for the dash, MPG. and the other I think goes to the air box.

There's at least 2 more things. 4th is the vacuum connection to the brake servo. That's the rigid, darker/shinier pipe. And 5th, which I think you can see with the terminal connection in the pic, is a high idle air bypass valve.

Its really hard to make out because the pic is so huge, you have to scroll back & forth trying to follow pipes, instead of being able to see all the pic on one screen.

hope its better…



the car has came with a open Airfilter..
is it better to change it to its original air filter?

thenks..

1 - narrow pipe to distributor, or fuel economy meter (dash)
2 - blanked off. This is okay.
3 - large pipe to connect one way valve to inlet manifold
between 3 and 4 is a one way valve
4 - to brake servo

If you don't have a fuel economy meter, then you'll not need a vacuum connection to it (obviously). Later cars had a couple of additions like high idle bypass, vacuum-operated enrichment switch, etc but these aren't in the pic.

I`m very matter about my fuel economy… but i dont whant it to damaged my power.
What is a "vacuum connection"? how do i connect it back?

The blanked off pipe , whare is it connected to?

I`ll like to get my car to the original condition as much as it possible…

Is yours a UK model? Sorry, I only know about UK models, I'd be guessing if its not. I'd rather not guess and then you go and connect or disconnect something, or try to find something that isn't there, etc. so I can't really help out, sorry.

what will hapen if i will disabul that?

maybe nothing, the extra vacuum is held as a 'reserve' for the vac operation of the a/c distribution box. if you remove it you may find there is not enough vacuum power to operate the a/c correctly. there is no reason to delete it, just make sure nothing is leaking!
