The screw holding the tank cap magnet has loosened. It was so lost I couldn't use my finger to turn it. It will eventually come off completely and fall into the filler neck, so I pushed it down and split the magnet into three parts. The cap fits well, but it doesn't seal very well as there are three ribs on the neck that prevent the o-ring from making a 360 degree seal, leaving a gap for dirt to enter. It's still better than Rams plastic plugs.
