Default Deleting Smog, Extra Vaccum Line Question

Hello all,

I have already read through 10 or 15 smog delete threads so please don't ask me to search.

I have attahced two pictures of what it is that I am talking about. I was getting ready to take off the thermactor and thermastor on the passenger fender wall (or whatever they are called) along with the associated vaccum lines and plug it at the engine (since I read that that whole vaccum tree, thermactor and thermastor can go). However, when i pulled away the wire loom, i saw that attached to the red vaccum line is a fitting that splits the line into the red and a blue line. The blue line runs into the fender well and I have no idea where it goes to.

My question is then, where does the blue vaccum line run to, and is that OK to delete along with the rest of the smog junk, or do I need to cut off the fitting and attach the blue line directly to the vaccum source (bypassing the vaccum tree)?

Thanks in advance!

once the vacuum sorce is plugged at the engine, you can remove those items with little worries about vac leaks. You will however likely cause a CEL. This could also trigger some side effects in the way the car runs, since you are only mechanically deleting the equipment, but not changing the reference data in the ECM.

I ordered a plug in device from rjminjection to Tell the ECM that the erg is closed so that I will not encounter this problem. So the blue vac line going into the fender is also smog related and can go? If you don't mind my asking-what does it go to?

Thanks for your help as always adder

again... once you remove the vac source, its all non functional anyway.... so why keep it?

and congratulations on spending what... $60... on a piece that you could have duplicated with $5 worth of resistors from radio shack... Please start consulting us before wastng your money.

Well since I don't know where it's going, as it is not part of the thrrmactor or thermastor, I am not sure if it is something important which I need to keep functional by affixing the vacuum source directly to the blue line, as opposed to capping the vaccum source. but by knowing what it is going to i may be able to make an informed decision.

That line goes to a plastic ball that is mounted in the fenderwell. On the inside of the ball is a rubber diaphram that divides the ball into two chambers. When the car is running, the vacuum line that is attched to it sucks on the diaphram and you'll also see a check valve in line with it. So when you shut the engine off, the ball acts as a vacuum storage tank. My advice is to leave it alone. You can remove all the lines that run the thermactor system and just retain the one line with the check valve in place that runs to the vacuum ball.

Ah I see thank you for your detailed response. Glad I know what that is now haha.

And adder- it was $20. I am terrible with electric and I know about the resistor route, but decided to opt against it to make my life that much easier.
