I need help locating where several hoses should be connected. I have attached several pictures. I believe I have some hoses crossed.

1.As Reed VLV side near firewall
2.To Hose on firewall looks like to gas tank/ fuel pump
3.Power brake booster
4.
5.
6.
7.hose with check valve from VSV for AS port closes to fender
8.VSV for FPU port closes to fender
9.To Valve Cover PCV Valve I think
10.VSV for FPU port closes to engine
11.VSV for EGR port closes to fender
12.VSV for EGR port closes to engine
13.

I have a 4th VSV type valve in picture 2 and 3 that i cannot identify or can figure out where hoses go

I have 2 hoses that are connected in a rubber sleeve that appear to be some type of drain

Also are 7 and 8 interchangeable or does it matter.


This engine has been sitting for about a year are sound like a woodpecker is inside. Also will not rev up. Slowly gains engine speed.


Thanks in Advance....I have search the internet and manuals.

Hey. Check under the hood. There is a small diagram that shows the vaccum horses..I will post some pics of my engine when I get home.

KHIG

I think the truck has been wrecked and front end rebuilt .... no stickers or diagrams at all.

See if your truck has a 4th VLV on the fender ..none of the diagrams I have found have one.

Thanks Ken

I thought I would post a picture of the diagrams..These only have 3 VSV valves...Mines has a 4th bolted on riight in front of the VSV for EGR valve

norcal707

ok this the one I have under the hood. I also have some pics of the vaccum lines on my runner.

Here's another good diagram I just came across.

I think the 4th valve you are looking for is the a/c idle up valve. Look at the picture of the under the hood diagram I think its called idle up valve.

KHIG

OK I hate to admit this but the year is wrong...see its my sons truck he told me it was a 95 but it's a 1994...I don't know if this matters....
The idle up switch on the vacuum diagram (from the fender) does not show all of the the vacuum lines.
And the picture betelnut posted has what appears to be a idle up switch part 17630 but the hoses are not clear which hose actually hooks to where...one side has a dotted line that goes to the bottom of a "y" pipe but does it matter which line.... and where does the other go?
my valve is Air condintion and heat idle up control valve like the one in the attached picture....when hoses go into rubber sleeve on drawing which is which when they come out?
These replies have helped but i still need help... if you can look at the picture that i have with the numbers on them. i need pictures where hoes to 4 ,5 , 6, and 13 go ...I need both ends of the hose

The truck it now running a little better it will respond to the throttle where as before it was flat and would not tack up at all..

KHIG

5 days of looking for where these hoses go and I finally found the vacuum ports on the steering pump...

Does it matter where the lines go?

It doesn't matter which hose is on the nipples on the PS valve. The other ends go to numbers 5 & 13.

KHIG:

Here are all the hoses on the pass side of the plenum. The item numbers correspond to your picture with the numbers in the first post. Toyota numbered the vacuum hoses and it looks like yours are still numbered correctly from your pictures. The vacuum hoses are the small hoses and the larger hoses are air hoses, fuel hoses, brake booster, and PCV hoses. I list the Toyota vacuum hose numbers as printed on the the hose itself as well as where it goes. Front and rear refer to the truck front or rear. There are three VSV's (rear, center, and front) and one AC idle up valve.

1. Reed valve
2. Fuel return hose
3. Brake booster
4. Rear air hose at the AC idle up
5. PS pump valve
6. Front air hose at the AC idle up
7. Vac hose #1 to pass side of rear VSV
8. Vac hose #2 to pass side of center VSV
9. PCV hose
10. Vac hose #5 to driver side of center VSV
11. Vac hose #3 to pass side of front VSV
12. Vac hose #6 to driver side of front VSV
13. PS pump valve

Vac hose #4 goes from driver side of rear VSV to the reed valve

AC idle up vacuum hoses:
- pass side to diaphragm (very short hose)
- driver side tee's into vacuum hose #2 (item 8 in your picture)

Hope this helps,
Bugs

Bump. Don't know if the OP saw the complete hose routing.

KHIG

Wow Thanks a bunch...Truck is running great now except wipers are not working..

Maybe it was sitting so long ...might just need a tap or a nudge.

I do have one more question ..there are 2 plugs in the harness going to oil pressure sending unit...... there is a green and a green with white stripe..... anyone know where it goes?

so what year is the BIG diagram on this page for? it looks about like the one i HAD for my '92...i saved it just in case


and BUGS1961....you're pretty amazing LOL!!! subscribed for future reference

In the big diagram there is a part labeled 23262. I need to know where the other hose, not the one that attached to the fuelrail line, attaches to. It is labeled "*#." I know usually *# means it has something to do with emissions, so my guess is the charcoal canister. Can anyone verify this?

I too am dealing with a 3VZ swap. What a pain...

EDIT:
Nevermind, got it.

Rickster1031

Just what I needed. I have a hose connected to the EGR valve that is completely blocked off. Didn't know what it was called to replace it. Thanks for the pic.

This write-up saved my sanity. Thanks Bugs!!

betelnut

Bugs rocks. I'm about to post a write-up where I found yet another application (removing transfer companion flanges) for his crankshaft pulley tool.

Thank you guys for the previous posts. I labeled the hoses and took a couple of pictures before my 3vze swap but I must admit to stupidity or something. What does the (bvsv) 23262 do on the back of the engine? It comes from the small port on the vacuum canister and goes through the vacuum valve to the air intake? I have ordered one of these, But I still want to know what it does. Right now my engine kicks down at 2000 rpm.

This is just what i was needing, an actual picture of the intake with lines labeled because the pictures I took were useless.
