Question What vaccum line is this?

I noticed this disconnected line on my 94 while my toddler was pointing at things and asking what they are. I havent had a chance to bust out my FSM or see if there is a vaccum when the car is running on it.

Keep in mind this car has its secondary system deleted.

The line from the vacuum pump would have gone into it.

Thanks, geezer. Hopefully the other end goes to a check valve or is just disconnected. I'll double check if it is creating a vacuum leak or not.

Sure that?s not the TB coolant that runs along the plenum?

that's the vacuum line from the pump to the SPT actuator solenoid. It almost looks like it's plugged? If the pump isn't running continuously, then it might be plugged down there too.

You're right, that does look like something is in the end. I'll take a look tonight.

That's gone, nothing to run.

I confirmed that is a plug in the end of it.

I can't remember, are your secondary throttles deleted?
