1991 3FE - Non US Vacuum Diagram (1 Viewer)

[12bit]

I've read several comments regarding the EGR system in the 3FE (and other engines) being a US specific environmental concession. Does there exist a toyota vacuum diagram for non US 3FE engines without the smog system in place?

I've got a de-smogged 3FE (1991 FJ80) and I am thinking about deleting the vacuum hard line assembly under the intake. Mine is extremely corroded and many of the ports are capped off anyway. I'd like to do away with it and run the remaining required vacuum lines directly. Looking for ideas on how best to approach and route things.

Thank you.

I understand the 3F to be carbureted where the 3FE is fuel injected. Would the vacuum logic be the same between them?

You don't need hardly anything for vacuum lines on a desmogged 3FE. I eliminated all the hardlines under the manifold. I kept the fuel pressure VSV and relocated it with a bracket onto the intake manifold, but some people have even removed that VSV and noticed no ill effects. My vapor canister is plumbed directly to my fuel tank and then just vented to atmosphere.
