Delphi HM10175 Direct Injection High Pressure Fuel Pump

The Delphi HM10175 is a high-pressure direct injection fuel pump engineered for Chevrolet and GM 2.4L gasoline engines. This engine-mounted pump delivers the precise high-pressure fuel required by modern gasoline direct injection (GDI) systems, operating at pressures ranging from 290 to 2,176 PSI to ensure optimal fuel atomization and engine performance.

Key Features:

• Designed for 2.4L GM Ecotec engines with direct injection technology
• Engine-mounted high-pressure pump driven by camshaft
• Operates at variable pressure from 290 to 2,176 PSI depending on engine demands
• Built to OE specifications with Delphi's proven fuel system engineering
• Compatible with E85 and gasoline fuel systems
• Rectangular connector design with 2-pin blade terminals

What's Included:

• High-pressure fuel pump assembly
• Mounting gasket and seal (on select applications)
• Mounting hardware (bolts and retainer on select applications)

Delphi is a Tier 1 OE supplier to major automotive manufacturers and has over 100 years of fuel system expertise. Each pump is engineered to meet or exceed original equipment standards for reliable fuel delivery, proper pressure regulation, and long service life. The HM10175 crosses to GM OE part number 12641847.

Installation Note: Proper installation requires pre-tightening mounting bolts evenly to ensure the pump plunger is perpendicular to the camshaft before final torque specification. It is recommended to clean the fuel system and replace the fuel filter when installing a new high-pressure fuel pump to prevent contamination-related failures.
