A-Premium Direct Injection High Pressure Fuel Pump for 2.4L GM Engines — with Gasket & Bolts, Rectangular Connector

A-Premium Direct Injection High Pressure Fuel Pump replaces the engine-mounted high-pressure pump to restore proper fuel rail pressure for compatible 2.4L GM engines.

This precision-engineered high-pressure fuel pump is made to meet the demands of direct injection gasoline engines that require elevated rail pressures. It arrives with the required gasket and mounting bolts, a rectangular electrical connector and two blade terminals, and fits many Buick, Chevrolet and GMC models using the 2.4L L4 motor. Before purchasing, confirm low rail pressure or diagnostic codes so you install the correct component for the issue.

How do I know this pump fits my vehicle?

Fitment is specific to 2.4L L4 engines used across multiple GM models and years. Match the part reference numbers and verify the engine code or year range on your vehicle before ordering.

• Compatible models include Buick LaCrosse (2010–2016), Regal (2011–2017), Verano (2012–2017).
• Also fits Chevrolet Captiva Sport, Equinox, Impala, Malibu and Orlando across specified years.
• GMC Terrain 2.4L examples covered for 2010–2017.
• Reference numbers: EP1028, GDP103, M73109, 12641847 and related OEM IDs.

What connectors, ports and hardware are included?

The pump ships complete with its sealing gasket and mounting bolts so you can replace the engine-mounted unit without sourcing extra fasteners. It uses a quick-connect inlet and a threaded outlet to match the existing fuel line layout.

• Rectangular electrical connector with two blade terminals for plug-in installation.
• Inlet outside diameter: 0.375 inch, inlet thread M14-1.5.
• Quick-connect inlet style and threaded outlet type—matches factory fuel plumbing.
• Included gasket and bolts for a full high-pressure pump swap.

When should I replace the high-pressure fuel pump instead of the in-tank pump?

This part specifically addresses failures in the engine-mounted high-pressure pump used for direct injection systems. If diagnostics point to low fuel rail pressure or engine codes related to the high-pressure circuit, replacing this pump is the appropriate step.

• Check engine codes P0087 or P0088 that indicate low or inconsistent rail pressure.
• Confirm measured fuel rail pressure is below factory specification before replacing.
• Mechanic verification of HPFP malfunction reduces the risk of unnecessary returns.
• Not a replacement for an in-tank fuel pump or the entire fuel module assembly.

Are there any installation tips or precautions I should follow?

Proper alignment and bolt sequencing are important to ensure the plunger aligns perpendicular to the camshaft and the pump functions reliably. Use the included hardware and follow recommended torque procedures or have a qualified technician install the unit.

• Pre-tighten bolts on both sides together, then evenly torque to final specification.
• Ensure pump body plunger is perpendicular to camshaft before final tightening.
• Replace the gasket and inspect mating surfaces for cleanliness and damage.
• Bleed the fuel system per vehicle service manual after installation.

Who is this for: This A-Premium high-pressure fuel pump is intended for owners and technicians working on GM vehicles equipped with the 2.4L L4 direct-injection engine who have confirmed high-pressure pump-related symptoms or diagnostic codes. If you have verified low fuel rail pressure, need an on-engine HPFP replacement, and want a kit that includes the gasket and bolts, this is a compatible, drop-in aftermarket option. Avoid purchasing if your problem lies with the in-tank pump or an unrelated fuel system component.
