KAX High-Pressure Fuel Pump HM10008 for 2.4L GM Engines — Direct Fit, Includes Gasket & Bolts (2010–2017)

The KAX HM10008 is a high-pressure fuel pump built to OE specifications for 2.4L GM engines, delivering steady fuel pressure and a direct fit for multiple GMC, Chevrolet and Buick models from 2010–2017.

If your 2.4L GM vehicle is experiencing hard starts, unstable idle, or reduced engine responsiveness, the fuel delivery system may be the cause. The KAX HM10008 is machined to match factory interfaces and mounts, includes gaskets and bolts, and replaces several OEM part numbers so technicians and DIYers can restore proper high-pressure fuel supply without modification.

How does this pump match OE performance and fit?

KAX manufactures the HM10008 to mirror the original pump’s interface, mount points, and hydraulic connections so it installs without adapting hoses or brackets. Internal precision parts are selected to maintain constant pressure under typical operating conditions.

• Rectangular electrical connector and quick-connect inlet (M14-1.5)
• Threaded outlet matching factory fittings for leak-free hookup
• Same mounting flange and bolt pattern for direct replacement
• Supplied gasket and bolts to simplify installation

What improvements or symptoms can this pump address?

Replacing a failing high-pressure fuel pump with a correctly spec'd unit helps stabilize fuel delivery and can resolve a range of drivability symptoms stemming from inconsistent pressure. This pump is intended to restore original system behavior, not to alter engine tuning.

• Helps eliminate hard starting caused by insufficient rail pressure
• Reduces idle surging or rough idle from unstable fuel flow
• Restores expected throttle response and engine power under load
• Prevents intermittent fuel cut-offs related to pump failure

What should you know before and during installation?

Proper installation is important for longevity and reliable operation. The pump is backed by a 2-year unlimited-mileage warranty, but attention to alignment and torque during fitting reduces the chance of early failure.

• Pre-tighten bolts evenly to keep the pump plunger aligned with the camshaft
• Confirm connector type and inlet/outlet thread sizes before installation
• Use supplied gasket and bolts to ensure correct sealing and mounting
• Check for any stored codes and clear after replacement if appropriate

Who is this for? The KAX HM10008 suits mechanics and knowledgeable DIY owners who need a direct OE-style replacement for the high-pressure fuel pump on GM 2.4L platforms. Choose this unit if you want a component that matches factory interfaces, arrives with required hardware, and is backed by a two-year warranty—ideal for restoring reliable fuel rail pressure and typical drivability.
