Hello, new to the T-bird world! My 2003 threw a p0442 code. Researching the code, and this forum, I replaced the gas cap and want to replace the purge valve. The parts were cheap enough, and I need to get it through state emissions inspection.

The question I have is, how do I remove the vacuum lines? I don’t want to break or lose the retaining clips, so I figured I’d ask before proceeding. Thanks in advance!

After replacing, I reset the codes and have driven it about 40 miles. So far, so good. I’m going to drive it around again today and bring it back for state inspection tomorrow. Hopefully, the check engine light doesn’t come on when I’m heading there like it did the last time!
 
You will need to do close to 90 or more to clear the tattle tale code that indicates the OBDC has been reset. It is so cars that have thrown a code don’t just have a code cleared before the test. Happens if you disconnect the battery or reset a code.
 
Once I knew how to take the lines off, it was extremely easy. There’s not a lot of wriggle room to manipulate the valve around, but I’ve done jobs that were a lot worse. It’s a 15 minute job from opening the hood to closing it.
 
Curious, is there no way to "trick" the system to not show a leak when there is one? seems like there should be a pressure sensor or something that could be jumpered out. Not trying to bypass the system or anything but, as these cars get older the ability to fix stupid things like these may get harder and harder.

I don’t think there’s any way to do this without “tampering with an emission control device”. Fortunately, for this particular part, there are several options readily available.
