The Cummins 3910120 Oil Gauge Tube is a component designed for use in heavy-duty trucks. It serves a specific function within the engine’s lubrication system, providing a means to monitor the oil level accurately. This monitoring is significant for maintaining engine health and ensuring optimal performance ¹.

Basic Concepts of Oil Gauge Tubes

An oil gauge tube is a component that facilitates the measurement of oil levels within an engine. It operates by allowing oil to rise within the tube to a level corresponding to the oil in the sump. This level is then translated into a reading on the oil gauge, providing the operator with information about the current oil level. Accurate readings are vital for the proper functioning of the lubrication system, as they enable timely oil top-ups or indicate potential issues such as leaks ².

Purpose of the Cummins 3910120 Oil Gauge Tube
