Honestly, this was one of the easier mods I've done. I found a test pipe was more time consumings of an install because of the moving of the O2 sensor. The specialty O2 sensor socket I bought started to strip it, so I used vise grips instead.

But I could see how this install would be difficult. If you work from the top-down, you'll probably need to remove the fan and maybe part of the UICP. Working from the bottom-up is the untraditional method, but if you don't have an undertray and have small hands, it is easier.

 

Where can I purchase new vaccum lines?

 

Autozone, Advanced Auto, NAPA or any auto parts store.
