Does the 6.4 Hemi have a fuel filter?
Yes—the 6.4-liter Hemi has a fuel filter, but it’s not a stand-alone inline filter you service separately. The filter element is integrated into the fuel pump module inside the fuel tank, so maintenance typically means replacing the entire pump module rather than swapping a separate filter.
Across the Challenger and Charger models equipped with the 6.4L Hemi, as well as the Jeep Grand Cherokee variants that use this engine, the fuel system design places the protective filter inside the pump assembly in the tank. This article explains where it sits, how it’s serviced, and what owners should know about maintenance and diagnosing fuel-delivery issues.
Location and design
In the 6.4 Hemi, the fuel filter is part of the fuel pump module housed inside the fuel tank. There is no traditional external inline filter to replace at intervals. When the filter needs service, technicians typically replace the entire fuel pump module, which includes the filter element as part of the assembly.
In-tank fuel pump module
The module sits in the tank and supplies pressurized fuel to the engine. Because the filter is integrated into this sealed module, it is not a user-serviceable, standalone component in most maintenance scenarios. This design is common across 6.4L Hemi applications in Dodge/Chrysler/Fiat products, including the Challenger, Charger, and Grand Cherokee variants that use the 6.4L engine.
Maintenance and replacement considerations
Below are key facts to keep in mind about serviceability and maintenance for the 6.4 Hemi’s fuel filter.
- Location: inside the fuel tank as part of the fuel pump module
- Service approach: when service is necessary, the typical repair is replacing the entire pump module rather than a separate inline filter
- Model scope: applies to 6.4L Hemi-equipped Challenger, Charger, and Grand Cherokee variants
- Replacement considerations: if the filter is suspected to be clogged or the pump is failing, plan for pump-module replacement rather than a stand-alone filter replacement
In practice, routine maintenance for this part of the system centers on fuel quality and drivability symptoms. Regular roadside fueling is unlikely to involve filter changes, but poor quality fuel or long service intervals can influence the lifespan of the pump module and its integrated filter.
Symptoms and diagnostic tips
If you’re experiencing fuel-delivery issues, these diagnostic considerations can help determine whether the pump module or screen is at fault.
- Symptoms: engine stalling, hesitation, surging, hard starting, or reduced power that may indicate low or inconsistent fuel pressure
- Diagnosis: measure fuel pressure with proper equipment and compare to the vehicle’s factory specifications for the 6.4L Hemi
- What to do next: if pressure is consistently low or erratic, the pump module (which includes the filter) is a likely culprit and replacement of the module is typically advised
- Safety note: depressurize the fuel system and follow all service manual procedures when accessing the pump module
Because the filter in this engine is integrated with the pump, many owners won’t replace the filter separately. Diagnosis and repair should be guided by the service manual or a qualified technician to ensure proper fuel-system safety and reliability.
Summary
Bottom line: the 6.4 Hemi does have a fuel filter, but it resides inside the fuel pump module in the tank rather than as a serviceable inline filter. When service is required, replacements involve the pump module, not a standalone filter. Maintaining good fuel quality and addressing fuel-delivery symptoms with professional diagnostics helps protect the system and keep the 6.4L Hemi performing at its best.
