2018 Chrysler 300 Fuel Pump Replacement: Complete Cost Guide and What Every Owner Needs to Know

The bottom line: If you own a 2018 Chrysler 300 and need a fuel pump replacement, you should expect to pay between $600 and $1,400 for the total repair, depending on your engine type, whether you choose OEM or aftermarket parts, and where you take the car. The fuel pump itself usually costs between $250 and $700 for an OEM Mopar part, and labor typically runs $150 to $600 depending on your shop’s hourly rate and how the pump is accessed.

Your 2018 Chrysler 300 is equipped with an in-tank fuel pump module, which means the pump sits inside the fuel tank. Accessing it usually requires removing the rear seat cushion or, in some cases, dropping the fuel tank entirely. While this is a moderately involved repair, understanding the cost structure and what to expect can save you money and headaches.

What Is the Fuel Pump and Why Does It Matter?

The fuel pump in your 2018 Chrysler 300 is a small electric motor located inside the fuel tank. Its job is to deliver pressurized gasoline from the tank to the engine. Along the way, the fuel passes through a filter — either inside the tank or externally in the fuel line. Most fuel pumps last for the life of the vehicle, but they can fail over time due to wear, contamination, or running the tank low on fuel regularly.

Common signs of a failing fuel pump include:

  • Engine struggles to start or won’t start at all — If you turn the key and hear no brief humming sound from the rear of the car, the pump may not be receiving power or may be dead.
  • Sputtering or hesitation at highway speeds — A weak pump can’t maintain consistent fuel pressure.
  • Loss of power under load — Going uphill or accelerating hard may cause the engine to choke.
  • Whining noise from the fuel tank — A healthy fuel pump is quiet; a loud whirring sound is a warning sign.
  • Check Engine Light comes on — This can indicate low fuel pressure or other fuel system issues.

If you ignore these symptoms for too long, your engine will eventually fail to start. It’s best to address the problem as soon as you notice any of these warning signs.

How Much Does a 2018 Chrysler 300 Fuel Pump Replacement Cost?

For a 2018 Chrysler 300, the total cost of replacing the fuel pump typically falls into the following ranges. These numbers are based on real-world estimates from repair shops, mobile mechanics, and parts retailers.

Total cost range (parts + labor): $600 to $1,400

Breakdown by component:

1. Parts cost (fuel pump module assembly)

  • Aftermarket pump module: roughly $100 to $300
  • OEM Mopar pump module: roughly $250 to $700
  • Complete kit with sending unit and O-ring: $300 to $900

For a 2018 model specifically, the Mopar genuine fuel pump module kit (Part # 68367534AB) retails for around $320 to $484 from dealers, and the fuel pump/level unit module (Part # 68494735AA) is priced at about $233 to $348.

2. Labor cost

  • Typical labor time: 2 to 4 hours for most models; 4 to 6 hours if the fuel tank must be completely dropped
  • Hourly shop rate: $75 to $150 per hour, with higher rates in major metro areas
  • Estimated labor cost: $150 to $600

3. Other potential costs

  • Shop supplies, disposal fees, and taxes can add $20 to $50
  • If the mechanic needs to drain the fuel tank or perform diagnostic work, that may add extra charges

Real-world example: Kelley Blue Book reports that for a 2016 Chrysler 300, the fair repair range for a fuel pump replacement near Ashburn, VA is $980 to $1,285, with dealer estimates around $980 to $1,083 and independent shops at $1,161 to $1,285. The 2018 model should be very similar.

What Affects the Final Price?

Several factors can push the cost higher or lower than the typical range. Understanding these will help you compare quotes more effectively.

Engine type and pump compatibility. The 2018 Chrysler 300 is available with the 3.6L Pentastar V6 or the 5.7L Hemi V8. While the pump mechanism is similar, part numbers and availability can differ slightly, which may affect the price. Always verify compatibility with your VIN.

Access method. On most 2018 Chrysler 300 models, the fuel pump is accessed through an access panel under the rear seat cushion. This is the easier, faster approach. However, if the vehicle has a different tank configuration or if the access panel is blocked, the mechanic may need to drop the entire fuel tank — which adds significant labor time and cost.

OEM vs. aftermarket parts. OEM Mopar parts are more expensive but come with a factory warranty and guaranteed fit. Aftermarket parts from brands like Delphi, Bosch, or Spectra Premium are cheaper and still reliable, but you should check warranty terms carefully.

Location and shop rates. Urban areas and dealer service centers charge higher labor rates — often $100 to $150 per hour. Independent shops in rural areas may charge $75 to $100 per hour. Mobile mechanics like AutoNation Mobile Service can sometimes offer competitive pricing and the convenience of coming to your home.

Vehicle condition and age. Rust, corrosion, or difficult access on older vehicles can increase labor time. If the fuel tank has debris or contamination, the mechanic may recommend additional cleaning or replacement of related components.

Where to Get Your Fuel Pump Replacement

You have several options for getting the repair done, each with different pros and cons.

1. Chrysler dealership. Using a dealer means you get genuine Mopar parts, factory-trained technicians, and a warranty on both parts and labor. However, this is the most expensive option, with total costs often at the high end of the range ($1,000 to $1,400+).

2. Independent repair shop. Independent mechanics typically charge lower labor rates than dealers and can use either OEM or high-quality aftermarket parts. Total cost is often in the $600 to $1,000 range. Just make sure you ask for an itemized written estimate that includes parts, labor, and any additional fees.

3. Mobile mechanic service. Companies like AutoNation Mobile Service come to your home or office and perform the repair in your driveway. They offer upfront pricing and a warranty. For example, AutoNation reports average costs for a Chrysler 300 fuel pump replacement at $628, with specific quotes for 2013-2014 models ranging from $359 to $986 depending on location and mileage.

4. DIY replacement. If you are mechanically inclined, replacing the fuel pump on a 2018 Chrysler 300 is a manageable DIY project. The pump is accessed through an access panel under the rear seat, so you don’t need to drop the tank. The DIY cost is roughly $165 to $270 for the parts and tools, compared to $600 to $1,400 for professional installation. However, you must be careful to relieve fuel system pressure, disconnect the battery, and work in a well-ventilated area away from open flames. A service manual for your specific year is highly recommended.

How to Get a Fair Price and Avoid Overpaying

Follow these tips when planning your 2018 Chrysler 300 fuel pump replacement:

  • Get multiple itemized quotes. Ask at least two or three shops for a written estimate that breaks down the cost of parts and labor separately.
  • Ask about warranty coverage. Find out if the parts come with a warranty (typically 1 to 2 years) and whether the labor is covered.
  • Check if the quote includes diagnostic labor. Some shops charge extra for diagnosing the problem before starting the repair.
  • Verify the part number. Make sure the quoted part is compatible with your exact VIN and engine configuration. Using the wrong pump can cause drivability issues or damage.
  • Consider using a high-quality aftermarket part. If you don’t need the absolute cheapest option, a brand like Delphi or Bosch offers excellent reliability at a lower price than OEM.
  • Be wary of unusually low quotes. If a shop quotes you $300 for the whole job, they may be using cheap parts or cutting corners. Always read reviews and check the shop’s reputation.
