This weekend I installed the JK Evap Skid Plate from Poison Spyder on my 2011 JKU. Sorry for not taking pics along the way.
Upon arriving at my house the box was pretty chewed up and mangled, but everything was packed well and there was no damage to any of the parts. The kit comes with the skid plate, a back plate, a top strap, mounting hardware and instructions. The instructions list most of the tools needed for the install although a flat head screw driver is not listed but is needed to remove the stock mounting bracket once you have the evap canister off the vehicle. Also I didn't have a 16mm open wrench, so I used a 5/8ths and it worked just fine.
After unplugging both of the connectors from the back of the evap canister, I attempted to remove the evap line but was unable. So I decided to try the install without removing the evap line. Everything went smooth following the included instructions until I got to the part where you need to mount the skid plate with the front two factory bolts. This would be much easier to do with a second person and possible even easier if you jack up the Jeep. I have a stock suspension and just crawled under my Jeep. After trying to get the first bolt finger tight through the wrench slot in the front of the skid plate I decided to try and reach my left arm from the rear inside the skid plate, while holding the skid plate with my right arm. This made getting the first two bolts finger tight much easier. I was then able to slide the evap canister with the evap line still attached into the skid plate and complete the install without any further problems.
Make sure to read the instructions carefully, as I didn't and initially installed the back plate on the outside of the skid plate, then re-read the instructions when the rear factory mounting hole didn't line up. So I had to go back and remove the three screws that hold the back plate in place and re-install the back plate correctly.
Overall a very easy install that took me 1 1/2 hours. Would have been much faster without my mistake on the back plate installation. You could also cut down on time with a second set of hands and if you have a lifted Jeep, or jack it up a bit.
