The 5323S01792 dial capsule is the direct read replacement for 6700 series “fixed length” gauges. The fuel level is depicted in 1/16 increments. The case is hermetically sealed by ultrasonic heating to melt and fuse the case into a solid piece. This keeps weather out, ensuring “no-fog” readability while greatly extending mechanical life. This seal is a high reliability, no-gasket design. The plastic case is capable of withstanding vibration and shock.
