Just a heads up: Chrysler tried to fix this problem a few times in production. Apparently there are three or four different setups for the check valve (where it was placed, angle of which it was mounted, and type of valve etc). Call the dealer first and set up an appointment. When you call, make sure that they check your VIN with the parts department. My dealer informed me that some of the vehicles get the TSB walk through. Others get a new check valve or filler neck. My Nitro however gets a new filler neck, check valve, and fuel tank. MORAL OF THE STORY: call first so that the dealer can order the parts specific to your VIN to save yourself time and further aggravation.
