Hello all. I have searched and searched, but I can't find the answer. On a stock air intake, where does the little vacuum hose closest to the radiator hose supposed to go? I bought a 240 that has been left in a field for the last 10 years. I got it running, but I have no idea where this vacuum hose is supposed to go. Thanks in advance

Pic would help.

There is a big hose on the bottom of the intake.

Then there is a small one that should go to the IACV under the throttle body.

Thought the iacv gets its vacuum from one of the four vacuum lines off of the vacuum canister and runs underneath the air intake.

Nope IACV goes directly to the intake tube.

Quick google pic search, here is the hose for the IACV and would go to the intake tube. Believe with aftermarket intake tubes it would be Tee'd going to the Valve Cover vent as well.

In stock form there are separate hoses for the IACV and Valve Cover Vent (then the rest of the tubes going to the intake tube are removed with all emissions deleted):

Thanks for the help, but thats not the hose. I have that one hooked up correctly. Its the little hose next to it. You can see it in the bottom picture. From left to right: radiator hose, intake tube, hose I need.

Believe that goes to one of the emission connections under the throttle body.

Probably google searching "KA24DE emissions" pics may be your best bet.

That's the problem. Ive been searching like crazy. No one seems to know. All my vacuum ports under the throttle body are connected to the vacuum canister on the drivers side fender. I just cant find that one connection anywhere.

I've removed all mine or I'd look at one of mine.

Would take someone with a mostly stock car to look.
