Replacement DH31450038 Direct Injection High Pressure Mechanical Fuel Pump

The Replacement DH31450038 is a direct injection high-pressure mechanical fuel pump designed as a reliable OEM-equivalent replacement for Hyundai and Kia gasoline direct injection (GDI) engines. This pump is responsible for pressurizing fuel from the low-pressure circuit to the high-pressure levels required by the GDI fuel injectors, ensuring precise fuel delivery and optimal combustion efficiency.

This pump replaces OEM part numbers 353202G720 and 353202G730, as well as aftermarket cross-reference number CHM10016, making it a straightforward drop-in replacement for the original unit.

Key Features:

• Direct injection high-pressure mechanical fuel pump — cam-driven design
• Designed to meet or exceed OEM specifications for fit, form, and function
• Rectangular blade-type electrical connector with 2 terminals
• Inlet fitting thread size: M14-1.5
• Compatible with 2.0L and 2.4L GDI four-cylinder gasoline engines
• Replaces OEM part numbers: 353202G720, 353202G730
• Aftermarket cross-reference: CHM10016

This high-pressure fuel pump is a critical component in gasoline direct injection systems. When the original pump fails, symptoms can include hard starting, rough idle, reduced power, and poor fuel economy. Replacing it with a properly spec'd unit restores normal fuel system operation.
