Airaid MIT Install Question
I have done the free FMU mod on my Runner, so my vacuum hose was re-routed from the intake to the boost port. The Airaid kit ships with a threaded fitting that you are supposed to use to connect that vacuum hose to. What have you S/C'd guys with the Airaid kit done to plug this hole on the tube? Did you buy a threaded plug for it, or go for a homemade plug? tia
Edit: Here is a picture to show you what part of the tube I'm talking about

I used a vacuum cap like Elton suggested. If I go back to stock for some reason it will be really easy to re-route the hose. Thanks for your suggestions.

Here is one of the Airaid MIT installed:
And one of the 2.2" URD Pulley:
And one of the runner for good measure:

If you skip that line the EVAP will vent under the hood - those are gas fumes from the fuel tank. If you just plug the line at the canister, pressure will build up, and it'll vent through the gas cap. Not good.

On a side note: In Bob_98SR5's writeup on the ISR mod, he talks about the power steering pump hose that comes out of the intake silencer box. He says in the very last paragraph of this link: https://www.yotatech.com/forums/f130/intake-silencer-removal-mod-3rd-gen-4runner-2000-a-75168/ to re-route that hose to the FPR. My truck did not have the power steering pump hose going to the intake silencer, and the port on the silencer for the PSP hose was capped. Is this normal? The writeup he did was for the same year truck, so I presume we should have a very similar setup under the hood. Does anyone know why my truck would have already had the PSP hose re-routed? tia

The PSP hookup is to a vacuum switch that's in the PSP that kicks the pump into a higher output so that you can get more assist in turning at lower speeds. For this to work, one line should be hooked up to either side of the TB.
