URO 000-476-04-21 Fuel Injection Accumulator for Mercedes-Benz

The URO 000-476-04-21 Fuel Accumulator is a critical fuel system component designed to maintain consistent fuel system pressure and flow for reliable engine operation and easy starting. This accumulator maintains pressure in the fuel system for a period of time after the engine has been switched off, facilitating re-starting, particularly when the engine is hot. When the engine is running, it serves to deaden the noise of the electric fuel pump, providing quieter operation.

Key Features:

• Manufactured to OE accumulator dimensions to ensure compatibility with original mounts and fuel line connections
• Quality materials resist engine heat and harsh fuel system environment
• Factory pressure-tested for reliability
• Keeps residual pressure in the fuel system, helping the engine re-start in high temperatures and preventing vapor-lock
• Direct replacement for Mercedes-Benz OEM part number 000 476 04 21

A failing fuel accumulator can cause hard starts, rough idling, extended cranking, or fuel odor near the engine. Replacing a worn accumulator restores proper fuel system pressure retention and improves starting reliability.
