Product Details

The Replacement RS31450004 is an electric fuel pump module assembly designed as a direct-fit OEM replacement for select Subaru Legacy, Outback, and Impreza models equipped with the naturally aspirated 2.5L 4-cylinder (H4) engine. This complete assembly restores proper in-tank fuel delivery and fuel level sensing to factory specifications.

Key Features:

  • Complete fuel pump module assembly with integrated sending unit
  • Includes fuel pump, fuel sending unit, and strainer
  • Non-turbocharged (naturally aspirated) applications only
  • Designed to meet or exceed OEM fit, form, and function
  • Direct drop-in replacement — no modifications required

OEM / Cross-Reference Part Numbers:

  • Subaru OEM: 42021AG110, 42021AG12A
  • Also cross-references: 42022AG150, E8651M, FG1255, P76427M, SP4057M

Replacing a failing fuel pump module assembly addresses common symptoms such as difficulty starting, engine sputtering, hesitation under acceleration, and inaccurate fuel gauge readings. This assembly restores consistent fuel pressure and flow for reliable engine performance.
