Shop with Blessed Performance for the Exergy Performance Rail Pressure Sensor for your 2001-2004 GM 6.6L LB7 Duramax diesel. The fuel pressure sensor is a crucial part of the high pressure fuel system. It effectively measures fuel pressure allowing for proper pressure control from the ECU. A faulty or failing sensor can cause serious running issues and potential system failure due to over pressure. If the connector is broken or cracked, water could be introduced to the terminals also causing incorrect information relayed back to the ECU.
Note: Standard LB7 connector with the factory male M12x1.5 fitting. Only to be used for LB7 applications. A professional diagnosis is recommended to ensure the rail pressure sensor is the cause of your issues. If mis-diagnosed and the rail pressure sensor does not fix your issue it cannot be returned once it has been installed.
