4Y-C Engine Vacuum System (Diagram & Photos)


Recommended Posts

Hi all.

I am having some trouble trying to correctly sort out the vacuum hoses in my Hilux. Now, i have managed to source a diagram for it (attached), but I haven't been able to follow it very well. For example, according to the diagram, there are about 5 different vacuum lines that go into the side of the carby, but the diagram is not very descriptive of which one is which (refer to photo - attached). As for the rest of the system, it would appear that I am missing the "EGR" part of the setup, will this matter much?

I was wondering if anyone could post some photos of their vacuum system on their motor so that I can get a better idea of what goes where and sort this system out properly.

Thanks in advance for any help.
