Well if you look at your engine, you will see two loop around lines, these are vaccum lines. I would replace them also. Anyways follow them toward your firewall and you should see a "bottle" like valve, this is the two way check valve. One end goes to your cruise control and the other goes toward your firewall. If you look at the picture attached, I have circled where you should look at first. If you go to Autozone or Advanced Auto, they probably won't know what this two-way check valve is. It isn't an automobile specific part, so their computer system won't do you any good. The valve is a cheap $3 part in the "Help" section of them stores, commonly stocked, right there on the shelf.
