We are now offering the main level unit (gauge sender) for the main pump (LH side) for the Hemi cars 11+. The reason for this is if you have a 2010 (and even some early 2011) and you want to add one of our drop-in assemblies, it is smart to just get 11+ (New style) FORE hat and buy late model sender as early model sender is no longer available and make the complete conversion. If your vehicle is a 2011 model, it would be a good idea to pop assembly out of tank and double check if your level unit is a round ball (early style) or a longer flat (new style). Another important note is that while a new assembly from the dealer is a little cheaper than this, it does not come with pins and wires, we searched for hours to find the correct pins and provide them with a 12" lead of fuel approved 20ga wire as well so the early model car owners can make this conversion as simple and painless as possible!
