When i installed my header i used duct tape and zip ties to plug the vacuum lines that went in to the bottom of my air box, but i figure there has got to be some better way to cap them off. I was just wondering what other people have used to plug these holes. Thanks.

 

Try using marine grade silicone.

 

Go to your local parts store, Autozone, Advance, whatever, and look for some vacuum line plugs. They are just little rubber caps and are usually different colors depending on size. I bought a variety pack of those and was able to cap off most of the lines on the air cleaner. There are a couple of large lines that you'll have a hard time finding vacuum plugs for. I never thought about doing this before but you might try putting on one of those replacement rubber feet for a chair leg (like you'd have on a stool or something). They are pretty big around and may fit some of the larger vacuum lines.

What I would really recommend you do is just permanently plug the vacuum lines. I took a grinder and cut off all the lines from the outside of the air cleaner. One of them I had to use a drill on. Then I cleaned up the inside of the air cleaner as well where some of the lines stick up. After cutting drilling and grinding them all out you'll have some holes left over. Go to your local parts store and buy a container of JB stick weld putty. You can cut off a piece, knead it up in your hands and plug the holes that are left over. The JB weld putty works very well and will probably be stronger than the rest of the air cleaner. Also, while you are doing surgery make sure that you cut out the flapper that goes in the snout of the air cleaner. It is very restrictive and you want it out of there.

Now, since you have ugly gray patches of JB weld all over your pretty blue air cleaner you want to paint it to match right? Well it just so happens that you can get a can of "Ford Blue" engine enamel by Dupli-color. It is almost a perfect match to the stock blue of the factory air cleaner. I don't know if most people know this or not, but I found out by accident. If you want to give your air cleaner patches a quick dust, go pick up some of this paint. It is a near perfect match. I did all this to my air cleaner and it looks like it came from the factory that way. I am working on a second version of the air cleaner right now where I opened up all the sides for more air flow. It will still look like a factory piece but it will flow way better. I'll post pics when I am finished with it.

 

Here are the vacuum line caps. The package I bought has almost this many in it, but they look exactly like this. These will plug most of the lines that you have left over after the rats nest removal. But like I said before, after doing mine and going through the pain of finding all the right plugs, I would just cut the lines off of the air cleaner and plug the holes.

The stick JB weld and can of blue paint is wayyy cheaper and easier than wasting a whole weekend running around town trying to find different sizes of little rubber caps. Save yourself the headache and just permanently remove them. It looks better when you get done anyway...

 

Thanks for the input. I got some small vacuum caps for the few little small hoses. I guess I'll try the JB weld if finding big vacuum caps turns out to be too much of a hassle.
