I have a 2009 Big Horn. I looked under the driver's side under the bed and couldn't find it. Is it more forward towards the transmission? I'm having a PO455 large evap leak code. I'm trying to locate the leak. If you know where the other components and hoses are for the evap system, please let me know.

 

It's under the cab from what I remember. I could see it when I stick my head up in there next to the frame.

 

Have to pull the bed or drop the tank.
