The Radium Engineering fuel level switch is a stainless steel sender with a specialized float and 1/8 NPT thread that functions in common vehicle fuels, including E85. The switch closes when the float moves, providing a reliable tank-level signal for compatible Radium fuel systems. Its corrosion-resistant construction is intended for in-tank or inline installations that accept the 1/8 NPT level switch.
