Replacement RN31450003 Fuel Pump Module Assembly with Sending Unit 2.5L 3.5L Sedan

The Replacement RN31450003 is an electric fuel pump module assembly designed as a direct OE-style replacement for the Nissan Altima Sedan equipped with 2.5L four-cylinder or 3.5L V6 engines. This complete module integrates all critical fuel delivery components into a single, drop-in unit, restoring proper fuel pressure and consistent engine performance.

Common symptoms of a failing fuel pump module include engine sputtering, difficulty starting, stalling under load, or a complete no-start condition. Replacing the full module assembly — rather than just the pump — ensures all wear components are renewed simultaneously for lasting reliability.

Key Features:

• Complete electric fuel pump module assembly with integrated sending unit
• Includes fuel pump, sending unit, float, fuel strainer, and tank seal
• Designed for OE fit, form, and function — no modifications required
• Compatible with both 2.5L L4 (QR25DE) and 3.5L V6 (VQ35DE) engine applications
• Resistant to ethanol-blend fuels and corrosive fuel contamination
• Engineered to match OEM pump housing, harness plug, and float sender alignment
