Hey guys, i own 2007 dodge caliber and have an issue for some time. Fuel gauge shows empty fuel tank even its half full.. also check engine light comes on with gascap message. Prevous owner somehow took somekind of valve from the fuel tank, so I am wondering maybe it is the issue? Also scan tool says that there is a small leak in evaporate system. The thing is that i dont know how that valve could look like, where it is located and also cant find any parts on the internet..
