Fuel Pump for 2013 Chrysler 300: Complete Guide to Replacement, Symptoms, and Costs
The bottom line: If you own a 2013 Chrysler 300 and your engine is struggling to start, hesitating during acceleration, or stalling unexpectedly, the fuel pump is likely the culprit.

The fuel pump is located inside the fuel tank, accessible through an access panel under the rear seat or by lowering the tank. This guide covers everything you need to know—symptoms, part selection, replacement steps, and cost-saving tips.
How to Tell If Your 2013 Chrysler 300 Fuel Pump Is Failing
The fuel pump in your 2013 Chrysler 300 is an electric pump mounted inside the fuel tank. It delivers pressurized gasoline from the tank to the engine's fuel injectors. Over time, the pump wears out, and certain warning signs will appear before it fails completely.
Common symptoms of a bad fuel pump include:
- Engine hard to start or won't start at all – A failing fuel pump cannot maintain proper fuel pressure, making it difficult for the engine to fire up.
- Loss of power during acceleration – When you press the gas pedal, the engine may feel sluggish or "choke" because the pump isn't delivering enough fuel.
- Engine sputtering at high speeds – If the car jerks or stumbles while cruising at highway speeds, the fuel pump may be struggling to keep up.
- Poor gas mileage – A weak fuel pump forces the engine to run inefficiently, leading to lower fuel economy.
- Whining noise from the fuel tank – A healthy fuel pump runs quietly. If you hear a loud whirring or humming sound coming from the rear of the car, the pump is likely failing.
- Check Engine Light comes on – The engine control module detects low fuel pressure and triggers the check engine light.
Important: If you smell gasoline or see fuel leaks, do not drive the car. Have it towed to a shop immediately.
2013 Chrysler 300 Fuel Pump Replacement Cost Breakdown
Part Costs
The price of a fuel pump assembly for your 2013 Chrysler 300 depends on whether you choose an OEM Mopar part or an aftermarket alternative.
- OEM Mopar fuel pump module (includes sending unit, strainer, and seal ring): $260 to $520. The OEM part number for the 2013 Chrysler 300 with a 5.7L or 6.4L engine typically falls under 68041381AB or 68103913AA.
- Aftermarket fuel pump assembly (brands like A-Premium, Herko, ECCPP): $40 to $350. For example, an A-Premium fuel pump module for the 2013 Chrysler 300 5.7L V8 is priced around $75 to $100. A Herko half-module (MM045) costs about $75.
- Remanufactured or used units from salvage yards or rebuilders: $70 to $180.
Which one should you choose? If you plan to keep the car long-term, an OEM Mopar unit or a high-quality aftermarket assembly is the best choice. The OEM part includes all necessary components—pump, sending unit, strainer, and seal ring—and is designed to match factory specifications.
Labor Costs
Labor charges vary by shop and location, but the typical range is:
- Labor time: 2 to 4 hours
- Hourly rate: $75 to $150 per hour
- Total labor cost: $150 to $600
Total Estimated Cost
| Component | Low End | High End |
|---|---|---|
| Part (aftermarket) | $40 | $350 |
| Part (OEM) | $260 | $520 |
| Labor | $150 | $600 |
| Total (aftermarket part) | $190 | $950 |
| Total (OEM part) | $410 | $1,120 |
Note: The average national cost for a fuel pump replacement across all vehicles is roughly $611 to $894. For a 2013 Chrysler 300, expect to be within or slightly above that range.
What's Included in a Fuel Pump Module Assembly
When you buy a complete fuel pump module assembly, it typically includes:
- Electric fuel pump – The main component that pressurizes and delivers fuel
- Fuel level sending unit – Measures the amount of fuel in the tank and sends the signal to the dashboard gauge
- Fuel strainer (filter sock) – A fine mesh screen that prevents debris from entering the pump
- Seal ring or O-ring – Creates a tight seal between the pump module and the fuel tank
- Float and reservoir – The float arm moves with the fuel level, and the reservoir keeps fuel around the pump during low-fuel conditions
Important: Make sure the replacement part includes a sending unit. Some aftermarket pumps sell only the pump itself, which means you would have to reuse your old sending unit—and that's not recommended if the unit is already worn out.
Which Fuel Pump Fits Your 2013 Chrysler 300
The 2013 Chrysler 300 came with several engine options, and the fuel pump compatibility depends on the engine size and whether it's the left or right side of the tank.
Engine compatibility for the 2013 Chrysler 300:
- 3.6L V6 – Uses a fuel pump module with part numbers like 68102700AA, 68102700AB, or E7263M
- 5.7L V8 HEMI – Uses a left-side pump module with part numbers 68041381AB or 68103913AA
- 6.4L V8 SRT HEMI – Also uses the left-side pump module, same as the 5.7L
Position: For the 2013 Chrysler 300 with a 5.7L or 6.4L engine, the fuel pump is located on the left side of the fuel tank (driver's side). Some models with a 3.6L engine use a right-side (passenger side) pump.
Always verify compatibility with your vehicle identification number (VIN) before purchasing. The best way is to check your VIN against the manufacturer's parts catalog.
How to Replace the Fuel Pump on a 2013 Chrysler 300
Replacing the fuel pump is a moderately difficult job. If you are not experienced with auto repair, it is strongly recommended to have a professional mechanic handle it.
Safety first: Gasoline is highly flammable. Always disconnect the battery, work in a well-ventilated area, and avoid smoking or any open flames near the work area.
Step-by-step overview:
- Disconnect the battery – Remove the negative battery cable to prevent sparks.
- Relieve fuel system pressure – Locate the fuel pump fuse in the trunk fuse box and pull it out. Then start the engine and let it run until it stalls. This depressurizes the fuel system.
- Remove the rear seat base – On the 2013 Chrysler 300, the fuel pump access panel is located under the rear seat on the driver's side. Pull up on the seat cushion to release it.
- Remove the access cover – You will see a metal cover plate with a few bolts or screws. Remove them to expose the fuel pump module.
- Disconnect the fuel lines and electrical connector – Mark the fuel lines for reference, then carefully disconnect them. Also unplug the electrical harness.
- Remove the locking ring – Use a fuel pump removal tool or a brass drift to loosen the large locking ring that holds the pump module in place. Do not use steel tools, as they can create sparks near fuel vapors.
- Pull out the old fuel pump module – Carefully lift the module out of the tank. Note the orientation of the float arm and the gasket position.
- Install the new fuel pump module – Transfer the old seal ring if not included with the new unit, or use the new one provided. Place the new module into the tank, making sure the float arm doesn't hit the sides of the tank. Tighten the locking ring securely.
- Reconnect the fuel lines and electrical connector – Ensure all connections are tight and there are no leaks.
- Reinstall the access cover and rear seat – Replace the cover plate and seat cushion.
- Reconnect the battery – Reinstall the fuel pump fuse and reconnect the battery.
- Test for leaks – Turn the ignition key to the ON position (without starting the engine) to prime the fuel pump. Check for any fuel leaks around the pump module. If no leaks are present, start the engine and let it run for a few minutes while checking again.
Estimated installation time: 1 to 2 hours for a professional mechanic, 2 to 4 hours for a skilled DIYer.
Tips to Save Money on Fuel Pump Replacement
- Confirm the diagnosis first – A clogged fuel filter or a bad fuel pump relay can cause the same symptoms as a failing pump. Have a shop verify the pump is actually the problem before spending money on a replacement.
- Replace the fuel filter at the same time – If your 2013 Chrysler 300 has an external fuel filter, replace it along with the pump. This prevents debris from clogging the new pump.
- Consider replacing the fuel pump relay – The relay is a common failure point. It costs about $15 to $30 and is good practice to replace it when you do the pump.
- Buy the complete module, not just the pump – A complete assembly with the sending unit and strainer costs more upfront but saves labor if the sending unit fails later.
- Get multiple quotes – Shop around for both parts and labor. Prices vary significantly between dealerships, independent shops, and online retailers.
- Keep the tank at least a quarter full – After installing a new pump, running the car on a low fuel level can cause the pump to overheat and fail prematurely. The fuel in the tank cools and lubricates the pump.

Frequently Asked Questions
Can I drive my 2013 Chrysler 300 with a bad fuel pump?
It is generally safe to drive short distances, but the pump may fail completely at any time, leaving you stranded. If you notice fuel leaks or smell gasoline, do not drive the car.
Where is the fuel pump located on a 2013 Chrysler 300?
The fuel pump is inside the fuel tank. On most models, it is accessible through an access panel under the rear seat on the driver's side (left side).
How long does a fuel pump last in a Chrysler 300?
Most fuel pumps last between 100,000 and 150,000 miles, but they can fail sooner due to debris, running the tank low on fuel frequently, or electrical issues.

Why does my car still not start after replacing the fuel pump?
Check the electrical connections at the pump. On a 2013 Chrysler 300, the fuel pump connector has five wires. Verify that the black/orange wire (pin 4) has a good ground and that the dark blue/orange wire (pin 5) has power when the key is turned to the ON position. Also check the fuel pump relay in the front power distribution center.
Final Thoughts
A failing fuel pump on your 2013 Chrysler 300 is a repair that cannot be ignored. The symptoms—hard starting, loss of power, poor fuel economy, and engine sputtering—will only get worse over time. Replacing the pump with a quality part, whether OEM or a high-performance aftermarket option like KEMSO, will restore your car's reliability and performance.
