DENSO 550-3031 Electric Fuel Pump

The DENSO 550-3031 is an electric fuel pump engineered to deliver consistent, reliable fuel supply to the engine. Built on DENSO's decades of experience as an original equipment manufacturer, this pump is manufactured to OE-grade standards for a direct-fit replacement that installs correctly the first time.

Key Features:

• Proprietary Turbine Technology – Delivers fuel with minimal pressure pulsation for smooth, quiet operation
• Precision-Balanced Armature – Balanced at 3,000 rpm and re-verified at 8,000 rpm to minimize noise and vibration
• Open-Vane Impeller Design – More efficient than closed-vane competitors, requiring lower amperage while maintaining optimum flow rates over time
• Check Valve – Maintains consistent system pressure for superior hot fuel handling
• Relief Valve – Protects the fuel delivery system from over-pressurization
• Choke Coils – Minimize radio frequency interference
• First Time Fit® Construction – Designed for precise, hassle-free installation
• OE-Grade Durability – Engineered for extended service life meeting or exceeding OEM performance standards

DENSO is both an OEM and aftermarket supplier of fuel pumps, meaning the engineering expertise and quality control behind this part are identical to what goes into factory-installed components. The 550-3031 is an ideal replacement for a worn or failing in-tank electric fuel pump.
