Name that hose

Hey, found a pretty serious air leak. This hose, and one attached to it needs to be replaced. Anyone know what it's called?

What is a Hooty Snooter valve, Alex?


On a serious note, that's your HVAC control line. I believe it leaves that T and goes down to that plastic ball.

Whats going on with it?

Like CPF said, literally anywhere will have that hose. Its nothing special.

I bet you are having problems getting the dash vents off the defroster, That is why!

3/16 vacuum hose from the T to the firewall and T down to the ball,

Yes my front vents only defrost, that and also not very cold A/C. I just pulled it off, is it supposed to be fitted onto this screw with no hole? That can't be right

Look for a rubber fitting through the firewall. It runs through that fitting to the back of the heater control panel.

The hose on the screw goes to the ball directly below the AC dryer. Roughly straight down from the T fitting,

Alright, thanks a lot. My vents are strong now, just not quite as cold. So that hose really goes to a non hollow screw? What is the point of that?

No, don't think so.

Well, after all... what would Banacek say ?... “May be hard to believe... President Trump should rest easy and concede what was in fact a foregone conclusion: Another OLD MAN won with only about 50% of the Change Believers/Fools showing up."

If it isn't the one going to the ball (vacuum canister), it could be the supply. See diagram, it's the red line. All hoses should have no leaks for everything to work.

No, it's not supposed to be there. Some dumbass put it there because, well, they're a dumbass.

He told you where it's supposed to be; he meant the end that's on the screw.

The vacuum ball is a storage reservoir. It stores a small amount of vacuum to cover low vacuum conditions. Sudden acceleration by pressing the pedal to the floor causes this momentary loss of vacuum. The way your hose is run now terminated on the screw it has no reserve and the dash vents will cut out on hard acceleration.

If you look below the AC dryer you will see the round ball shaped reservoir. The hose attaches to the nipple on the reservoir. There is little working room and getting the hose on the nipple can be a pain. Probably why it was just plugged it onto a screw to stop the vacuum leak.
