The lift pump is located in the engine’s fuel system and is driven by the engine’s camshaft.

Another way to test a Cummins Isx lift pump is to listen for a whining noise coming from the engine. This noise is caused by the lift pump’s camshaft drive gear. If you hear a whining noise, it indicates that the lift pump is not properly lubricated.
Finally, you can also visually inspect the lift pump for signs of wear and tear. Look for cracks in the housing, worn or damaged seals, and any other damage. If you see any damage, it is likely that the lift pump needs to be replaced.
