May be a dumb question.  But if I removed the EGR and used the block off plate.  Which vacuum lines are still required.  It is hard to figure it out because all the diagrams seem like almost all the hoses are for EGR

Thanks for the help

I second that question, (above)

"Required?"

The vacuum/pressure line to the fuel pressure regulator is required.
The PCV line is also pretty much required.
The power steering idle-up line is generally a good idea.
The line to the charcoal canister is also a good idea, but should have a check valve so you don't inadvertently pressurize the canister.
I think the remaining lines are "optional". It really depends on how modified your motor is. The ECU assumes those other lines are in place and functional, but as you move further away from stock you also move further away from the stock tuning tables, so I think those other lines become less relevant.

Ron or someone else may be able to offer a more nuanced view.

Thanks for the response. Well ironically the 4runner I bought was scavngr (guy who asked question above). The motor has an rv head, cam, lc throttle body and k and n intake. Hope that helps. Thanks again for the help. Thanks kyle

Jeff hit all the gotta have's.  Basically if you loose the EGR, you can remove the metal vacume tube assembly attached alongside the passenger side of the valve cover, and all the hoses and bits that attach to it.  Really cleans up the engine...  At the bottom of this post is a link to my gallery, that shows my engine from the top minus EGR and all associated plumbing...

Cool. Thanks alot for the help. The egr has been remove already but when I got the truck it just wants runing 100 percent so I just want to check everything. Start with the vac lines. I will b posting other questions on tps, timing and mass air flow. Thanks again kyle

On the mother of all diagram photos, is 25806 (VALVE) necessary?  What does it do?  I'm cleaning out a bunch of lines and removed that when working on something and don't want to deal with it.

Also, can the charcoal canister line be moved to another port on the intake say towards the back where EGR once went to clean up the look?

Anyone know what it does?

I removed mine when I cleaned up my vacuum, hoses and went to a standalone system. Notice how I am not telling you what it does, as I was never completely sure.  ;D  But if you are using an aftermarket EFI system, you don't need it.

I even forgot where it went from and to lol.  Oh well.  I'll just disconnect most of it cap it and if it doesn't run figure it out from there.  What's the deal with the fuel rail?  That connects to ____ and raises the fuel pressure for 4x4 mode?

Guys on the back of my char coal canister on the inner fender well on the pass side there is a hose that comes out and goes down next to the frame. It doesn't connect to anything and im losing a ton of vacuum threw it. Where does it go?

I think it has to do with the Turbo LED and the FPU (Fuel-Pressure-Up).  This switches the DC Voltage from ~10V to 12V (full battery) to the fuel pump during boost. Somewhere I posited the fuel pressure differences...

Hey guys, sorry to bump this old topic, but I figured it would be useful to keep it all in one place.  This is the sticker from the hood of my 1986 2WD SR5 Turbo, 5 speed.  Truck has AC/PS, no cruise control.  Note that it does not have the canister and VSV that the others do, interestingly enough.
