Bosch 0580464008 - Electric fuel pump

Bosch 0580464008 Electric Fuel Pump – Overview

The Bosch 0580464008 is a high‑performance electric fuel pump designed for inline fuel delivery systems in a wide range of passenger and light commercial vehicles. It replaces older models such as the 0580464015 and 0580464019, offering improved reliability, efficiency, and compatibility with modern engine management systems.

Key Features

• High Flow Rate: Delivers consistent fuel pressure up to 250 psi, ensuring optimal combustion across a variety of engine sizes (1.3–5.3 L).
• Compact Design: Engineered for tight engine bay spaces, the pump’s dimensions are 140 mm × 120 mm × 80 mm.
• Durable Construction: Made from corrosion‑resistant aluminum housing and high‑grade stainless steel internal components.
• Integrated Pressure Sensor: Provides real‑time feedback to the engine control unit (ECU) for precise fuel metering.
• Low Power Consumption: Operates on a 12 V DC supply with an idle current of 0.5 A, reducing electrical load.
• Seamless Integration: Compatible with Bosch’s OEM fuel line assemblies and standard inlet/outlet fittings (1/4‑inch NPT).

Installation Guidelines

1. Disconnect the battery: Prevent accidental electrical activation during installation.
2. Remove the old pump assembly: Carefully detach inlet and outlet fittings, noting any gasket positions.
3. Prepare the mounting surface: Clean and inspect for corrosion; replace damaged brackets if necessary.
4. Install the new pump: Align the inlet/outlet ports with the 1/4‑inch NPT fittings. Tighten bolts to 80 Nm torque specification.
5. Seal integrity check: Verify PTFE O‑rings are seated correctly; replace if worn.
6. Reconnect electrical wiring: Ensure polarity is correct and secure connections with heat‑shrink tubing.
7. Test run: Reconnect the battery, start the engine, and monitor fuel pressure gauges for stable operation.

Maintenance & Troubleshooting

• Regular Inspection: Check for leaks at inlet/outlet connections every 10,000 km or annually.
• Electrical Checks: Verify voltage supply and monitor current draw; any increase may indicate internal wear.
• Pressure Monitoring: Use a pressure gauge to confirm the pump maintains target pressure under load conditions.
• Common Issues:
  • No Fuel Delivery: Inspect wiring, fuses, and inlet/outlet seals.
  • High Pressure Readings: Check for clogged fuel filters or incorrect sensor calibration.
  • Electrical Noise: Ensure proper grounding and use shielded cables if necessary.

Performance Benefits

The Bosch 0580464008 delivers several advantages over legacy pumps:

• Enhanced Fuel Efficiency: Precise metering reduces excess fuel consumption by up to 5 %.
• Improved Engine Response: Rapid pressure build‑up leads to smoother throttle response.
• Longer Service Life: Corrosion‑resistant materials and robust seals extend operational life beyond 150,000 km.
• Reduced Emissions: Consistent fuel delivery supports tighter emission control systems.

Conclusion

The Bosch 0580464008 Electric Fuel Pump is a reliable, high‑performance component suitable for a wide array of vehicles. Its compact design, durable construction, and precise fuel metering make it an ideal choice for both OEM replacements and aftermarket upgrades in modern automotive applications.
