location of the fuel pressure sensor .

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! On a 2002 Cadillac DeVille, the fuel pressure sensor is typically located on the fuel rail, not on the fuel tank. The fuel rail is situated on top of the engine, distributing fuel to the injectors. This sensor monitors the fuel pressure within the rail and sends this information to the engine control module (ECM) to help regulate the fuel pump and maintain optimal fuel pressure. If you're troubleshooting issues related to fuel pressure, inspecting the fuel rail on top of the engine is a good starting point. Good luck!
