Vacuum line diagram label is located under the hood, at the front. Look for it.
To fix this break,
goto your local auto/hardware store and pick up a pack of the correct dia size universal vacuum connectors and black rtv silicon.

 

Why do I need RTV silicon? Why can't I just attach the new rubber hose

 

You can do whatever suits you.
Your ride, your choice.

Khomer2, I appreciate your response. I am not trying to be argumentative, I am just trying to understand why use the silicon glue? What is so special about this connection.

I would still like to know why is there a smaller diameter pipe between the two end-points. There has to be a reason for it.

 

No argument intended.
rtv is optional, however, you want a tight permanent fit, yes? - it was a single continuous line previously (before it broke).

The vacuum line is for the fuel pressure regulator and the diverter valve for the air pump.
The end points are just HD connectors.

Watch n learn.

 

listen to khomer. he know what he's talking about. I have tried this w/o a proper sealant and leaks came back. little leaks are hard to detect and throws flags

 

How come the car is running fine with the broken hose. I cannot tell any difference at all. No engine lights either. If I had not seen the broken hose I would not even know about it

 

That might be a non-critical vacuum line like the lines that open door locks, AC, etc. Don't know your car's lines. Follow it to investigate.

 

How do you know it's running fine?
You not being able to tell the difference doesn't mean it's not an issue or becomes an issue.
How do you know you're getting the correct mileage? Vacuum plays a role too, in this myriad of connections under the hood.

When was the last time you scanned, ran live feeds and tested the vacuum system?
Scan and post your results.

Yes that is a very good point.

 

I just did a scan with my $10 OBDII scan tool. No faults. No pending or historical faults either. Like I said at least I cannot tell any difference in the car's performance

 

$10 scan tool. Sorry, doesn't cut it in my books.
Is the 'live feed' portion of this scanner one's own, 'can't tell the difference' commentary?

Respectfully, you get what you pay for.

It ha worked well in the past . Always given me correct fault codes for EGR valve, Transmission conductor plate, issue etc.

 

That cheapo scanner won't tell you anything useful for this situation.

 

Later I will go to AutoZone and get it scan there

 

That circuit may only be active during certain phases. I too have an inexpensive OBDII scanner $20 by Autel and it was able to tell me that the most likely cause of my 'check engine' (money light) light was a loose fuel cap.

Unhook that yellowed plastic line and go to Home Depot. Go to the plumbing section and look at the hard plastic water lines. There are a bunch of different sizes. It doesn’t need to be exact. find the line that the same size or slightly bigger and remove the old yellowed garbage and put the new piece in
You dont need to rtv silicone anything. The rubber is what seals the line by compression.

That was my first thought exactly. Went to Home Depot. They did have small diameter rubber pipe that looked very close to the Yellow garbage. But it was sold in large spools costing over $25. I thought that was too much money for a 4" hose. I guess I must not have gone to the plumbing section. Any way I got the job done for $8.

 

They sell the tubing in small 5/6 foot rolls and I think yiu can buy it by the foot also.

 

I use Teflon of the appropriate external diameter. Amazon or EBay. It’s cheap.
