[QUOTE="Sluggie24, post: 16043167, member: 184003"] I've been an auto tech for 25 years now. In my experience, unless the cap is left loose, the cap is only the EVAP leak about 5% of the time. Most of the time there is a leak elsewhere in the system or a bad sensor. It really depends on the vehicle as there are common problems with certain models once they get older. On the new edge they put a plastic "protector" around the metal fuel filler neck. Looks like wire loom . That collects road debris, dirt and sand in it. That debris holds water against the pipe which causes it to rot/rust. Eventually they get a hole which will throw EVAP codes. They also used a rubber grommet to seal the filler neck to the tank which was stupid. Over time it can dry rot, harden or shrink causing a leak which will throw codes. Can also be damaged if the tank was removed at one time. My advice would be to remove that plastic cover on the neck and look at the surface. It's only held on by zip ties. Dust any loose rust off and smell it to see if you detect a fuel odor. If you aren't sure go fill the tank on a dry day and look under there and see if the rusted section of pipe looks wet or damp right after filling. A hole the size of a pin prick will set a code. If you find a leak in the neck replace both the neck AND the grommet. Last I looked lmr had both on their website. [/QUOTE]
