In a 2010 Dodge Charger, there is a single fuel pump—an in-tank electric pump that feeds the engine via the fuel line. There is no factory second pump in standard configurations.
Overview of the Charger’s fuel system in 2010
The 2010 Charger lineup used a returnless fuel system with one electric pump located inside the fuel tank. The pump module supplies fuel to the engine through the fuel lines, while the regulator (where applicable) manages pressure from the engine bay. The system is designed for reliability and is typical of mainstream Chrysler/Mopar vehicles of that era.
What’s inside the in-tank pump module
Understanding the pump assembly helps when diagnosing fuel-supply issues. The module generally includes:
- In-tank electric fuel pump
- Fuel level sending unit (fuel gauge sensor)
- Associated wiring and mounting hardware
Note: The fuel pressure regulator for a returnless system is typically located in the engine bay and not in the tank; the pump module primarily handles delivering fuel and sending fuel-level information.
Maintenance implications
When the Charger needs a fuel-pump service, technicians typically replace the entire pump module rather than just the pump. This approach ensures the sending unit and wiring remain aligned with the fuel system’s pressure and level sensing requirements.
Common symptoms of fuel-pump issues
Relying on a single pump means symptoms of pump failure can be sudden. Watch for prolonged cranking, misfires, engine stalling, or no-start conditions, especially when the tank is low on fuel; fuel-starved symptoms often indicate pump or sending-unit problems.
Summary
The 2010 Dodge Charger uses one fuel pump, housed in a single in-tank pump module. This arrangement is consistent across standard trims for that model year, with maintenance typically involving replacement of the entire module rather than a standalone pump. Understanding the module helps in diagnosing fuel-supply issues and planning repairs.
