Vac hose delete guide?

[bonylad]

I came from the 4G63 world, and this info was widely available. Which lines were needed, which weren't. Ive done a search and either its not their or I didn't see it. Hoping to clean up the bay and delete the cruise control and all unneeded parts. So. Anyone have a vac. line delete guide? TIA!

All the vacuum lines are needed. Toyota didn't put time and effort into the system it doesn't need.

If you want to pull your CC, that is understandable as long as you are not doing road trips. That is a matter of convenience. Others have done it.

Agreed. I like everything to workie-workie.

On that CC topics, we need to cap the hardline by the firewall off right? and do we need to get a vented cap? I've read on this topic a longgg time ago and I think i can use a quick reminder. Thanks! What about the bvsv ?

 

[jetjock]

Only cap the tee leg that went to the CC actuator. The rest of the plumbing is needed for the heater core coolant valve. Now if by "CC" you're referring to the EVAP system then yes, cap the hard line from the gas tank and install a vented gas cap. The BVSV can be left in place sans hoses after capping the throttle body port.

I think one guy meant the cruise control, the other guy was thinking charcoal canister.

Got it. Edited. Another example why nomenclature is important...

.....I got nothing. Lol. Its common dsm usage to delete them. What is a good place to see what's what so far as what each line goes to other than a diagram? A vfaq? Or a common term FAQ?
