Narrowed to 2005-2009 GT 4.6L. Diagnose power, grounds, duty command, rail pressure, FPDM and pump current before replacement. This returnless PWM system needs wiring, injector, fuel pressure and calibration review for power upgrades. Full return-style systems are outside this page.
OEM numbers
Ford FPDM service reference 5L8Z-9D370-A with the stored supersession family. Checked pump modules: Holley 12-948 for 2005 and 12-949 for 2006-2009 Mustang GT 4.6LDeatschWerks 9-305-7230 for 2005-2009 S197 Mustang 4.6L. Stock in-tank OE module is not claimed.Supersession
FPDM service family resolves to 5L8Z-9D370-A in the checked catalog history. Drop-in pump modules have a hard 2005 versus 2006-2009 Holley split; they are upgrade paths, not Ford supersessions.
Fitment
Narrowed to 2005-2009 GT 4.6L. Diagnose power, grounds, duty command, rail pressure, FPDM and pump current before replacement. This returnless PWM system needs wiring, injector, fuel pressure and calibration review for power upgrades. Full return-style systems are outside this page.
Aftermarket options
Checked replacement FPDM path, Holley 300 LPH complete drop-in modules and DeatschWerks DW300 module. Holley explicitly supports PWM/returnless use and separates 2005 from 2006-2009. Fuel-system capacity claims require the full build and tune, not pump flow alone.
Before you buy
Limited to 2005-2009 GT 4.6L. Holley uses separate 2005 and 2006-2009 modules. Diagnose pressure, power, grounds, FPDM command and pump current first. Pump flow alone does not establish safe horsepower or tune compatibility.
