Vehicle & Engine Compatibility Matrix: 2010-2017 Chevrolet Equinox (2.4L Ecotec SIDI) High Pressure Fuel Pump 2013-2014 Chevrolet Malibu (2.4L Ecotec SIDI) High Pressure Fuel Pump 2010-2017 GMC Terrain (2.4L Ecotec SIDI) High Pressure Fuel Pump 2011-2017 Buick Regal (2.4L Ecotec SIDI) High Pressure Fuel Pump 2010-2016 Buick LaCrosse (2.4L Ecotec SIDI) High Pressure Fuel PumpHardware Physical Specifications: - Pump Type: Camshaft-Driven Mechanical High Pressure Pump - Inlet Port Thread: M14 x 1.5 - Connector: 2-Pin Rectangular (Regulator Solenoid) - Internal Components: Stainless Steel Plunger & SpringTechnical Restoration Characteristics: This GDI fuel pump addresses pressure drops in the high-pressure rail system. By restoring the precise mechanical energy transfer from the camshaft to the fuel delivery path, it maintains the structural integrity of the fuel spray pattern needed for direct-injection cylinders. All units are tested to match factory-specified pressure output curves.Mandatory Installation Advisory: Ensure the camshaft lobe is at its lowest position (Base Circle) before bolting the pump down to prevent internal plunger damage. High-pressure fuel lines are one-time use according to many factory manuals; please inspect lines for deformation. Relieve all fuel system pressure before beginning service. A new gasket must be used (included) to maintain a secure seal at the housing interface.Cross-Reference OE List: 12641847, 12633115, 12639694, 12608371, 12633423, GDP103, EP1028, HM10008, M73109
