ok well today I unplugged/broke my hvac *****..i was trying to take the whole thing out. Well.one of the things that came off sounded like a vac. hose. it made a pressure relief sound. ? is ..can I leave them out? I wont need them in the car and what do I do with the vacuum hose?-Mark

 

were you pulling them for good?

if yes, I would unplug the hose from the intake, and plug the intake

 

...yeah I guess so. Its going to be my daily summer driver..and i already took out the AC and I didnt turn on the controls once. Where on the intake does it plug in?

its the one that is labeled "to HVAC vacuum check valve"

 

is that evap thing part of emissions?

 

yes

 

Can you still run the EVAP with an aftermarket throttle body without the vaccume connection?

 

it needs to be run to a vacuum port, t/b or intake, but t/b prefered
