1G What are these hoses and should they be connected?

Hi all,

Just noticed these three small hoses are not connected, what are they and should they be?

And if so, what goes to what? I've looked in the service manual but can't see anything.

TIA!

Thank you very much!

What are the consequences of them not being connected?

Emission control wouldn't work and would cause vacuum leak. You have to block off those ports if you wouldn't connect those hoses.

What service manual? The above diagrams are directly from the service manual.

@Redongreenon on the inside of the car's hood (bonnet if you're English) there might still be a sticker that shows how the vacuum lines are supposed to run. It's similar to what was posted by DSMPT.

Just out of curiosity, what does the European and Japanese emission vacuum line layout look like? Was it the same as the USA Federal layout? Did the DSM's Federal emissions meet all the international standards?

Yeah mine still has that sticker.

Japanese is different. It doesn't have those ports on throttle body, there is only one port. The same for Galants, early EVOs etc. I don't know about European though.
