View Full Version : Reuse injector O-rings or buy new ones for install?

Im trying to drop in some TT injectors this weekend so I looked around for the O-ring part number on here. Came across the injector install on a4mods.com (link (http://www.a4mods.com/index.php?page=webcontent/pages/injectors.html&category=1)) and from how i read the writeup, you make sure to keep track of the rings and reuse them?

I know the new parts would be cheap and all, but I'd rather not have to drive to get them unless I have to

i would definitely recommend replacing them if you can. O-rings are wear items which will go out in time, its only a few bucks and a small amount of time. saves you a headache and an intake manifold covered in fuel. there isnt anything scarier than fuel leaking out of an injector and having a moment of fear that your car will ignite! To answer your question though, its not required to do so every time you take them out, but it can't hurt to do so- especially if they are old.
