Detailed Product Overview

The URO 0004760621 fuel accumulator is a fuel injection system component that helps stabilize pressure in the fuel delivery circuit after shutdown and during restart. By retaining pressure in the system, it supports reliable fuel delivery and reduces hard-start concerns on older Mercedes-Benz fuel injection setups. The low alloy carbon steel body is built for the heat and chemical exposure common in the engine bay, while OE-matched dimensions help preserve the original routing and mounting layout. This part number 0004760621 is a direct-fit service option for Mercedes-Benz 190E, 300E, 300TE, 300SE, 300SEL, 260E, and 300CE applications listed below.

This part cross-references URO 0004760621 for the same application.

Common Symptoms This Part May Address

• Hard starting after the vehicle sits
• Fuel pressure loss after engine shutdown
• Rough restart behavior on fuel-injected Mercedes-Benz models
• Inconsistent fuel delivery during warm or hot operation
• Pressure-related drivability issues in the fuel injection system

Installation Notes

Verify inlet thread diameter, port size, and overall length against the original unit before installation. Inspect fuel lines, sealing surfaces, and nearby mounts for wear or contamination before reassembly. Because this accumulator is built to OE dimensions, it is intended to align with original mounting points and fuel line connections on the listed Mercedes-Benz applications. Professional installation is recommended for fuel system service.

Quality Assurance

Each unit is factory pressure-tested and backed by a 24 Month Unlimited Mileage Warranty. URO manufactures this accumulator to OE-style dimensional standards to support proper fitment on the specified Mercedes-Benz fuel injection applications.
