11.8mm plastic hollow pepper ball and plastic floating ball are international standard fittings for fuel sensors, but because nylon plastic is sensitive to temperature, the volume of nylon pepper ball will change after the temperature rises, so the accuracy of nylon ball will also change.

The 11.8mm plastic hollow pepper ball used in fuel sensor must be dried before it can be used, otherwise it will produce defects when it is installed in fuel sensor, including the workshop where fuel sensor is assembled, which needs constant temperature and humidity. Only in this production environment can qualified fuel sensor be manufactured.
