CP4 Disaster Prevention Kit
Videos were helpful as were the included instructions, to a point. Seems like there are some variances from one model-year to another, subtle, but definite. Getting the back four bolts off the upper intake was a chore and my hands have the cuts to show how tight it was, at least for me.
I started off by snapping the retainer clip on the vacuum line quick connect because I didn't know how to release it...a little extra force is not always the answer. Here's the quick connect.
If you ever snap that little black clip, the Dorman 800-023 is the exact part you'd need to replace it. Got mine at Autozone.
I did have to read carefully and consult a few different sources to ensure I had installed the fuel line correctly and did have to move one line I had connected incorrectly - again small variances from what was documented in the instructions and what my vehicle actually resembled. Still after about 6 hours, not counting hunting down that little clip and running to buy a couple 1/4" drive extensions and a long Torx T25 bit (really needed to access the front FSA bolt on the top of the CP4), I had everything together and when I fired up the truck, no leaks, thank you Jesus! Yes, I did a lot of praying working on this, and some asking forgiveness for cussing some...no one's perfect.
All-in-all it was a moderately difficult job for me, but I'm glad I finally did it.
If you have any questions about your upcoming install, ask away, but don't wait too long, the memory isn't what it used to be!
Adios

To each there own, but I dont install the return filter kit. All it does is keep any metal from getting back to your tank... The factory filters do a great job at keeping anything left in the tank from getting back to the engine...
