Audi A4/Peugeot 405/Renault External Fuel Pump 0580464070 DK-047 Straight Tube Type

When your vehicle experiences power loss during acceleration, hard starting, or stalling while driving, especially when the fuel gauge shows normal level, this often indicates the external fuel pump core has aged and cannot maintain stable fuel pressure. When functioning normally, this part pumps fuel from the tank to the engine to ensure accurate mixture concentration and steady power output. Compatible models include Audi A4, Peugeot 405, and Renault series, with OEM numbers 0580464070 and DK-047. During installation, keep the fuel path clean to prevent debris entry, and ensure straight-pipe interfaces and hose seals are tight to prevent fuel leaks.
