What are the symptoms of a failing rail pressure sensor on a Duramax LB7?

Common signs include rough idling, hesitation or stumbling during acceleration, poor fuel economy, and illuminated check engine lights with fuel pressure related diagnostic trouble codes. If you notice these issues, the sensor is a good component to inspect.

Does this sensor come with any mounting hardware or seals?

This part is the rail pressure sensor itself. It is recommended to check your service manual or consult with a technician to see if any additional seals or hardware are needed for installation, as these are often separate items.

Is this sensor difficult to install on a 2001-2004 Duramax?
