In the Dodge Charger lineup, the fuel-delivery setup varies by engine and trim level. This article breaks down when a second pump is used and why it matters for maintenance and diagnostics.
Most Chargers use a single fuel pump in the tank to feed the engine, but the high-performance SRT variants, including Hellcat and Redeye models, employ a dual-pump module to meet the higher fuel demands of their powerful engines.
How fuel pump configurations vary across the Charger lineup
The Charger’s fuel system ranges from a standard single-pump setup on everyday models to a specialized dual-pump arrangement on the performance-focused variants. The exact configuration can depend on year, engine, and specific options, so it's best to verify for your exact vehicle.
Single-pump Chargers
These Chargers use one in-tank fuel pump module to supply the engine with gasoline. The module typically includes the pump, the fuel sender, and associated fittings in one assembly. This configuration covers most daily-drivi ng Chargers with engines such as the V6 or the less-demanding V8 setups.
Before listing specifics, note that this configuration is common for non-SRT trims and standard performance models, where the single pump provides adequate flow for normal driving.
- Common engines in this category include the 3.6L Pentastar V6 and many non-SRT V8 configurations.
- The fuel system relies on a single in-tank pump to meet the car’s standard power needs.
- Service/repair typically references a single-pump module rather than a dual-pump assembly.
In this configuration, the vehicle relies on one pump to meet typical driving demands, with no secondary pump involved in normal operation.
Dual-pump Chargers (high-performance SRT/Hellcat variants)
On the high-performance end, Chargers equipped with the 6.2L supercharged Hemi — notably SRT Hellcat and Redeye variants — use a dual-pump fuel module inside the tank. This design supports higher fuel flow and offers redundancy under strenuous conditions such as track use or full-throttle acceleration.
Before listing specifics, it’s important to understand that the dual-pump setup is characteristic of the SRT family and is designed to sustain extreme power output and fuel demand.
- Primarily associated with SRT Hellcat and Redeye configurations produced during the 2015–2023 model years.
- The two pumps operate to deliver higher fuel flow to the high-pressure rail during peak demand and boost events.
- Replacement or servicing often involves the dual-pump module rather than a single pump, due to the integrated design.
In dual-pump setups, both pumps are part of a single module, and service instructions typically reference the entire dual-pump assembly for replacement or diagnostics.
Maintenance and diagnostics for Charger fuel pumps
Regardless of configuration, basic fuel-system diagnostics include checking pump operation, fuel pressure, and electrical circuits. Symptoms of fuel-pump problems can include hard starting, stalling under load, or reduced performance at high RPMs. For dual-pump systems, ensure you verify both pumps’ operation and the integrity of the entire module, as issues may involve the module wiring, connectors, or a failure in one pump that affects overall flow.
When in doubt, consult the owner’s manual, a factory service manual for your exact model-year/engine, or a Mopar parts catalog to confirm whether your Charger uses a single-pump or a dual-pump module and to obtain the correct replacement parts and procedures.
Summary
In short, the Dodge Charger does not universally have two fuel pumps. Most Chargers use a single in-tank fuel pump, but the high-performance SRT Hellcat and Redeye variants employ a dual-pump fuel module to meet the greater fuel-demand of their engines. If you’re maintaining or replacing a Charger, confirm your exact model year and trim to determine whether you’re dealing with a single-pump or dual-pump configuration, and follow the appropriate service procedures.
