Detailed Description

Delphi FG1558 is engineered as a direct-style fuel pump module assembly for vehicles that use an in-tank electric pump with an integrated sender. It is built for gas fuel systems and includes the regulator, strainer, and float arm assembly needed to support fuel delivery and fuel level monitoring. For 2010-2013 Mazda 3 applications, this module helps restore proper fuel pressure and sender operation when the original unit is worn or inconsistent. Delphi’s OE heritage and broad aftermarket coverage are reflected in the component design and application focus. This part cross-references Spectra Premium SP4118M for the same application.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel pressure
• Engine hesitation or stalling related to fuel delivery loss
• Inaccurate fuel gauge readings from a failing sender assembly
• Fuel pump noise associated with a worn in-tank module
• Fuel starvation concerns from a restricted or aging pump assembly

Installation Notes and Tips

Fits 2010-2013 Mazda 3, N/A. Clean the fuel tank before installing the fuel pump to help prevent future seal problems. Verify outlet style, electrical connector type, and system pressure requirements before installation. The package contents include the fuel pump module assembly with float arm, seal, and instruction sheet; no lock ring or gasket/seal is listed as included beyond the seal noted in the package contents.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. FG1558 is built as a standard replacement fuel pump module assembly for select Mazda 3 applications and is backed by Delphi’s OE-oriented manufacturing approach.
