2013 Chrysler 300 Fuel Pump: Complete Guide to Symptoms, Replacement, and Cost
The bottom line: If you own a 2013 Chrysler 300 and suspect your fuel pump is failing, you should expect a total replacement cost between $410 and $1,120, depending on whether you choose OEM parts or aftermarket alternatives, and whether you do the work yourself or hire a professional. The fuel pump is located inside the fuel tank beneath the rear seat, and replacing it is a moderately difficult DIY job that takes 2 to 5 hours. Knowing the symptoms early can save you from being stranded and prevent costly engine damage.
Signs Your 2013 Chrysler 300 Fuel Pump is Failing
A failing fuel pump doesn't always give you a clear warning, but there are several common symptoms to watch for. If you experience any combination of these issues, it's time to inspect your fuel system.
1. Engine cranks but won't start. When you turn the key to the "run" position, you should hear a brief humming sound from the rear of the vehicle as the fuel pump primes the system. If you hear nothing, the pump may not be receiving power or may be completely dead .
2. Loss of power during acceleration. A weak fuel pump cannot deliver enough fuel under high demand, causing your Chrysler 300 to hesitate or struggle when you press the gas pedal, especially going uphill .
3. Engine sputters or stalls. If your car stalls unexpectedly but restarts after a few minutes, the fuel pump may be overheating and failing intermittently .
4. Whining noise from the fuel tank. A healthy fuel pump runs quietly. A loud whining or humming sound coming from the rear of the car indicates internal wear, and the pump is likely near the end of its life .
5. Long cranking time before the engine starts. If it takes several seconds of cranking before the engine fires up, the fuel pump may be losing its ability to maintain prime pressure .
6. Decreased fuel efficiency. A failing pump that cannot maintain proper pressure forces the engine to work harder, reducing your miles per gallon noticeably .

Where the Fuel Pump Is Located
The fuel pump in your 2013 Chrysler 300 is located inside the fuel tank, which is situated in the rear of the vehicle beneath the rear seat area . The good news is that you can access the fuel pump module through an access panel under the rear seat cushion, meaning you do not need to drop the fuel tank for this repair . This makes the DIY job significantly more manageable.
How to Replace the 2013 Chrysler 300 Fuel Pump (DIY Guide)
If you are mechanically inclined and have the proper tools, replacing the fuel pump on a 2013 Chrysler 300 is a manageable DIY project. Always work in a well-ventilated area away from open flames or sparks, and keep a fire extinguisher nearby.
Tools and Materials Needed
- New fuel pump module assembly (compatible with your 2013 Chrysler 300)
- 10mm socket and ratchet
- Flat blade screwdriver
- Hammer or rubber mallet
- Brass punch (to avoid sparks)
- Fuel line disconnect tool
- Safety glasses and gloves
- Shop towels and drain pan
- Fire extinguisher (highly recommended)
Step-by-Step Instructions
Step 1: Depressurize the Fuel System
Locate the fuel pump relay in the fuse panel under the hood. Remove the relay, then start the engine and let it run until it stalls. This releases all fuel pressure. If the engine does not start, crank it for a few seconds to relieve pressure .
Step 2: Disconnect the Battery
Loosen the 10mm nut on the negative battery terminal and remove the cable. This prevents any electrical sparks while working near fuel vapors .
Step 3: Remove the Rear Seat Cushion
The rear seat cushion on the Chrysler 300 pops out easily. There are small latches on either side of the seat, roughly in line with the seam. Give the seat a firm upward pull on each side and lift it out .
Step 4: Access the Fuel Pump Module
Under the rear seat, you will see a rubber access cover. Lift this cover to reveal the fuel pump module top. Pop off the harness cover and the main cover, then disconnect the electrical connector .
Step 5: Remove the Lock Ring
The lock ring securing the fuel pump module can be difficult to remove. Use a screwdriver and hammer to tap the ring counterclockwise. A brass punch is preferred because it will not create sparks. Be careful not to damage the plastic components .
Step 6: Disconnect Fuel Lines
Use the proper fuel line disconnect tool to release the fuel supply and return lines. Press the tool into the fitting and pull the line straight off. Expect some residual fuel to spill – have shop towels ready .
Step 7: Remove the Old Module
Carefully lift the entire fuel pump module assembly out of the tank. Tilt it sideways to allow excess fuel to drain back into the tank. Note the orientation of the fuel level float arm, as the new module must be installed in the same position .
Step 8: Install the New Pump
Transfer any reusable brackets and the pickup screen to the new pump module. Place the new O-ring seal into the groove on the tank opening. Insert the new pump module into the tank, being careful not to damage the fuel level sensor. Align the legs of the pump with the slots in the tank, then press down firmly. Install the lock ring and rotate it clockwise by hand, then use a punch and hammer to tap it into place securely .
Step 9: Reconnect Everything
Reconnect the electrical connector and fuel lines. Replace the access panel and reinstall the rear seat cushion. Reconnect the negative battery terminal .
Step 10: Prime the Fuel System
Turn the key to the "run" position and allow the fuel pump to run for about 2 seconds, then turn it off. Repeat this process three times to prime the system. Then start the engine and check for any fuel leaks .
Common Questions About the 2013 Chrysler 300 Fuel Pump
Q: How long does a fuel pump last?
Most fuel pumps last between 100,000 and 150,000 miles. Keeping your gas tank at least a quarter full helps cool and lubricate the pump, extending its lifespan .
Q: Does the 2013 Chrysler 300 have one or two fuel pumps?
The 2013 Chrysler 300 has a primary fuel pump module on the left side and an auxiliary module on the right side for certain fuel tank configurations, especially the 34-gallon tank .
Q: Can I replace just the pump, or do I need the whole module?
Most modern vehicles, including the 2013 Chrysler 300, use a sealed fuel pump module assembly. It is strongly recommended to replace the entire module, which includes the pump, fuel level sending unit, strainer, and O-ring. Replacing just the pump is difficult and often not reliable .
Q: Will a bad fuel pump cause a check engine light?
Yes, the check engine light may illuminate, and diagnostic trouble codes (DTCs) related to fuel pressure or system lean conditions may be stored .
