DeatschWerks 9-437-7034 X3 Module 1998-2004 Ford Mustang Base GT SVT Cobra DW430C

The DeatschWerks 9-437-7034 is an X3 triple pump module pre-loaded with DW430C brushless fuel pumps and a complete plumbing and install kit, engineered specifically for 1998 to 2004 Ford Mustang applications including Base, GT, GT Bullitt, Mach 1, SVT Cobra, SVT Cobra 10th Anniversary, and SVT Cobra R. The 9-437-7034 replaces the factory in-tank fuel pump module with a direct drop-in unit capable of supporting high-horsepower forced induction builds on pump gas or E85, requiring no cutting, welding, or fabrication to install.

Each DW430C pump inside the 9-437-7034 is manufactured by Bosch and flows 430 LPH at 40 psi, with a maximum pressure rating of 100 psi and a current draw of 14.8A at 13.5 volts. The DW430C pump features an advanced carbon matrix commutator for improved durability with E85 and race fuels, a digitally balanced armature to extend bearing life, and an integrated check valve to maintain fuel system pressure and avoid hard starts. The X3 module configuration retains all OEM fuel level sensing, surge bucket, and venturi functions so the factory fuel gauge operates correctly after installation.

Installation Notes

The 9-437-7034 is a drop-in replacement for the factory 1998 to 2004 Ford Mustang in-tank fuel pump module. The fuel tank on these Mustangs is accessed from the trunk floor. The module drops directly into the OEM tank opening and retains the factory fuel sender float arm for correct gauge operation. DeatschWerks recommends using a high-current relay kit to supply full voltage to the pump under all operating conditions. A return-style fuel system is required for proper operation. Professional installation is recommended on vehicles built for high power output.

Frequently Asked Questions

What vehicles does the DeatschWerks 9-437-7034 fit?
The 9-437-7034 fits 1998 to 2004 Ford Mustang models including the Base, GT, 2001 GT Bullitt, Mach 1 (2003 to 2004), SVT Cobra (1998 to 1999, 2001, 2003 to 2004), SVT Cobra 10th Anniversary (2003), and SVT Cobra R (2000).

How much power does the 9-437-7034 support?
The 9-437-7034 uses DW430C pumps flowing 430 LPH each at 40 psi with a max pressure rating of 100 psi. In a triple pump X3 module configuration this supports substantial high-horsepower forced induction builds on pump gas and E85. The actual horsepower ceiling depends on fuel type, injector size, and overall fuel system setup.

Are the DW430C pumps in the 9-437-7034 E85 compatible?
Yes. The DW430C pump features an advanced carbon matrix commutator engineered for long-term durability with E85, methanol, and race fuels. The 9-437-7034 is fully compatible with ethanol-based fuels.

Does the factory fuel gauge still work after installing the 9-437-7034?
Yes. The 9-437-7034 retains the OEM fuel level sender float arm assembly so the factory gauge reads correctly after installation with no additional wiring or calibration required.

Does the 9-437-7034 fit the SVT Cobra?
Yes. The 9-437-7034 fits the 1998, 1999, 2001, 2003, and 2004 SVT Cobra, the 2003 SVT Cobra 10th Anniversary Edition, and the 2000 SVT Cobra R. Note there was no 2000 regular SVT Cobra production model.

What is included with the 9-437-7034?
The 9-437-7034 includes the complete X3 module assembly with DW430C pump(s) pre-installed, a full plumbing kit, and a complete installation hardware kit. No additional parts should be required for a direct OEM replacement install.

Does the 9-437-7034 require a return fuel system?
Yes. A return-style fuel system is required for proper operation. 1998 to 2004 Mustangs with a returnless OEM system will need to be converted to a return-style setup before running this module at full capacity.

What is the warranty on the DeatschWerks 9-437-7034?
The 9-437-7034 is covered by DeatschWerks's 3-year no-fault warranty against defects in materials and workmanship. DeatschWerks's no-fault policy is among the most comprehensive in the performance fuel delivery market.

Is the 9-437-7034 a direct bolt-in replacement?
Yes. The 9-437-7034 is engineered as a direct drop-in replacement for the factory 1998 to 2004 Ford Mustang fuel pump module. No cutting, welding, or fabrication is required. The module fits into the OEM tank opening using the factory lock ring.

Is the 9-437-7034 CARB legal?
No. The 9-437-7034 is not CARB legal and is not for sale or use in California. It is intended for competition and off-road use only where permitted.
