Electric Fuel Pump Module Assembly For 2005-2019 Chrysler 300/Dodge Challenger/Charger/Magnum

Fuel transfer problems, an inaccurate fuel gauge, tank-side imbalance, intermittent stalling at a low indicated fuel level, or evaporative-system faults can involve the right-side tank unit, but the primary pump and electrical circuit must be diagnosed first. The BDFHYK E7279A is a right-side auxiliary fuel module and sender assembly for specified Chrysler 300, Dodge Challenger, Charger, and Magnum applications. It is not the left-side primary pump module. Confirm the right-side position, engine, fuel type, tank, flange, connector, float arm, and OE reference.

E7279A Right-Side Auxiliary Fuel Module for Chrysler and Dodge

Specified Vehicle Coverage

• Selected Chrysler 300 applications within the listed OE family
• Selected Dodge Challenger and Charger applications within the listed OE family
• Selected Dodge Magnum applications within the listed OE family

Exact model year, engine, fuel type, drivetrain, and tank configuration vary across the broad 2005–2019 catalog range. Confirm the VIN and OE number rather than assuming all vehicles within that range use the same auxiliary unit.

Confirm the Right-Side Position and Primary Pump Difference

Common E7279A/SP7050M configurations are installed on the right side as an auxiliary sender or transfer unit and do not replace the left-side primary electric pump module. Compare the locking flange, connector, outlet or transfer ports, reservoir design, module depth, float arm, and sealing surface with the removed right-side assembly.

E7279A OE and Interchange References

Common references include E7279A, E7264A, SP7050M, SP7083M, SP7088M, P76662R, FG1565, FT4018, 05136023AA, 05136023AB, 05136023AC, 05136023AD, 05136023AE, 68000605AC, 68145782AA, and RL136023AD.

Diagnose Transfer, Sender, and Pressure Faults

• Scan for fuel-level, evaporative-system, voltage, and fuel-pressure faults.
• Check the primary left-side pump module before replacing the auxiliary unit.
• Verify power, ground, connector condition, and sender-circuit continuity.
• Check fuel transfer between tank chambers where applicable.
• Separate a sender or transfer fault from a primary-pump pressure fault.
• Inspect the tank for water, sediment, damaged lines, or contaminated fuel.

Replacing the right-side auxiliary unit will not correct a failed left-side pump, control circuit, injector, ignition, or engine-management problem. Complete the appropriate diagnosis first.

Right-Side Auxiliary Module Installation Notes

1. Relieve fuel-system pressure and disconnect the battery.
2. Clean the right-side service opening before removal.
3. Record the connector, flange, transfer connection, and float-arm orientation.
4. Inspect the left-side primary module and transfer path when tank balance is abnormal.
5. Remove contamination and correct damaged tank or wiring conditions.
6. Install a new seal and secure the retaining ring correctly.
7. Keep the float arm and transfer components unobstructed.
8. Reconnect all lines and electrical plugs without forcing them.
9. Prime the system, inspect for leaks, and verify transfer and gauge operation.

Do not treat E7279A as a universal primary fuel pump. Match the right-side OE family and physical assembly before installation.
