Ok so awhile ago I ended up losing control and went backwards into a curb and hit a huge rock. got the back bumper replaced/evap canister/exhaust ect. After the wreck I had the CEL come on saying it was a evap system leak (large). The shop I had everything replaced at looked at it and said they found a small crack in one of the hoses and replaced it and reset the codes for me. It came back on 2 days later. I went back they said they had no idea why it was giving the leak and to take it to another shop and get it diagnosed .... Yea dont get me started with that haha.

Anyways I figured since my back end got hit hard Id assume the leak was coming from one of the hoses back there so I checked them myself and found a hose that wasent all the way in so pushed that in and the light stayed off for a week before it came back on. I tried to do some research on where all the hoses are for the evap system and couldn't find much so I don't know where else to check. From what ive read I know it connects to the fuel tank (the canister) and also up in the engine bay as well. Any suggestions? I want to do it myself if possible doesnt seem that hard to check for cracks in the lines but I could be wrong.

Here is a picture of my car when I messed it up.

 

I've not checked myself so I can't be certain the information you are seeking is on there, but have you checked the manuals that you can download on www.nicoclub.com?
