I have a 2010 Ford Fusion SE 2.5L. I have had repeated problems with the Check Fuel Fill Inlet gauge and more recently the Check Engine gauge. My code reader said code P0457. The valve is located in the front center under the hood. It attaches to the vacuum line, electrical connector, and two 8mm screws. This couldn't be easier to fix. The lights might stay on after the repair until the car starts, so I cleared the codes manually and it's been clean ever since. It was a very easy fix for me, less than 10 minutes and all systems are working! Save some money and do it yourself if you feel like you can. Much luck! UPDATE: It's been almost 6 months, 10,000 miles and still no problems. This part definitely fixed the bugs.
