Fuel Pump for 2015 Dodge Charger: Complete Replacement Guide and Best Options

f you own a 2015 Dodge Charger and are experiencing hard starting, engine stalling, or a whining noise from the rear of your car, the fuel pump is likely failing. The best solution is to replace the entire fuel pump module with a quality OEM or high-performance aftermarket unit. This guide covers everything you need to know about selecting, diagnosing, and installing a fuel pump for your 2015 Dodge Charger.

The 2015 Dodge Charger uses a returnless fuel system with the fuel pump located inside the fuel tank. The fuel pump is part of an integrated module that includes the pump, fuel level sending unit, and fuel filter. When any part of this module fails, replacing the entire assembly is recommended rather than just the pump alone. The factory fuel pressure specification for the 2015 Charger ranges from 58 to 62 PSI, depending on your engine configuration.

Common Symptoms of a Failing Fuel Pump

Recognizing the warning signs early can prevent being stranded and avoid potential engine damage. Here are the most common symptoms you may experience:

1. Hard Starting or Extended Cranking
If your Charger takes longer than normal to start, especially when the engine is hot, the fuel pump may be losing its ability to maintain prime pressure. The pump should produce a brief 1-2 second buzz when you turn the ignition to the ON position. If you don’t hear this sound, the pump, relay, or wiring may be faulty.

2. Engine Stalling or Sputtering
A failing fuel pump cannot deliver consistent fuel pressure. This causes the engine to hesitate, sputter, or stall during acceleration or at idle. You may notice power loss when climbing hills or merging onto highways.

3. Whining Noise from the Fuel Tank
A loud humming or whining sound coming from the rear of the vehicle is a classic sign of pump failure. While all fuel pumps make some noise, a failing pump produces a noticeably louder, higher-pitched sound.

4. Check Engine Light with Specific Codes
Common diagnostic trouble codes include P0087 (low fuel pressure) and P0230 (fuel pump circuit malfunction). These codes indicate the fuel system is not performing within specifications.

5. Loss of Power Under Load
When you accelerate hard or carry a heavy load, the engine needs more fuel. A weak pump cannot keep up with demand, causing hesitation or a complete loss of power.

Which Fuel Pump Fits a 2015 Dodge Charger?

The exact fuel pump you need depends on your engine size. The 2015 Dodge Charger came with several engine options, each requiring a specific pump assembly.

For 3.6L Pentastar V6 Engines
The OEM part number is 68102700AB or its superseded versions. This pump assembly delivers approximately 190 liters per hour at 60 PSI. Aftermarket equivalents include Delphi FG1655 and Bosch 69418.

For 5.7L HEMI V8 Engines
The OEM part number is 5136022AI or 68159764AA. This pump provides adequate flow for the HEMI’s higher fuel demands. Many aftermarket options also fit this application.

For 6.4L SRT V8 Engines
The 6.4L engine requires a higher-flow pump. OEM part numbers include 68367534AA or 68367539AA. These pumps maintain stable pressure under high-performance conditions.

Cross-Reference Compatibility
The 2015 Dodge Charger shares its fuel pump platform with several other vehicles. The same pump assembly also fits the Chrysler 300 (2011-2015), Dodge Challenger (2011-2015), and Dodge Magnum (2005-2008). However, always verify fitment using your Vehicle Identification Number (VIN) before purchasing.

OEM vs. Aftermarket Fuel Pumps: Which Should You Choose?

When replacing your fuel pump, you have two main options: genuine Mopar OEM parts or aftermarket alternatives. Each has distinct advantages and drawbacks.

OEM Mopar Fuel Pumps
Genuine Mopar pumps are engineered specifically for your Charger. They offer precise flow consistency with only ±2% variance, ensuring stable fuel pressure. The materials are corrosion-resistant, and the pumps operate quietly at around 50 decibels. OEM pumps come with a 2-year warranty from Mopar.

The downside is cost. OEM fuel pump modules for the 2015 Charger range from $300 to $600, depending on the engine and supplier. Dealership installation adds another $200 to $400 in labor, bringing the total to $500 to $1,000 or more.

Aftermarket Fuel Pumps
Reputable aftermarket brands like Delphi, Bosch, and KEMSO offer pumps that meet or exceed OEM specifications at a lower price point. Aftermarket pumps typically cost $120 to $250. However, quality varies significantly between manufacturers. Cheap, unbranded pumps may have flow rate variances of ±15%, which can cause lean fuel codes and engine performance issues.

For most daily drivers, a quality aftermarket pump from a trusted brand is an excellent choice. For high-performance or modified engines, consider upgrading to a high-flow aftermarket pump designed for increased fuel demands.

Step-by-Step Fuel Pump Replacement Guide

Replacing the fuel pump on a 2015 Dodge Charger is an advanced DIY job. Plan for 3 to 6 hours of work time. If you are not comfortable working with fuel systems, have a professional mechanic perform the replacement.

Safety Precautions
Always work in a well-ventilated area away from sparks, flames, or heat sources. Keep a Class B fire extinguisher nearby. Disconnect the negative battery cable before opening the fuel system. Wear safety glasses and nitrile gloves.

Required Tools

  • Socket set (8mm to 18mm)
  • Torque wrench (10-200 Nm range)
  • Fuel line quick-disconnect tool set
  • Fuel pump lock ring tool
  • Floor jack and jack stands
  • Drain pan and shop towels
  • Flat trim tool and needle-nose pliers

Step 1: Depressurize the Fuel System
Remove the fuel pump relay or fuse from the underhood fuse box. Start the engine and let it run until it stalls. Crank the engine for 3 more seconds to relieve any remaining pressure.

Step 2: Access the Fuel Pump
The 2015 Dodge Charger may have a service access cover under the rear seat. If equipped, remove the rear seat cushion by releasing the front clips with a flat trim tool. Lift the cushion out and set it aside. Clean the area around the cover thoroughly so no dirt falls into the fuel tank.

If your Charger does not have a service cover, you must lower the fuel tank. Support the tank with a floor jack, remove the tank straps, and carefully lower it enough to access the pump module.

Step 3: Disconnect Fuel Lines and Wiring
Unplug the electrical connector from the top of the pump module. Use a fuel line quick-disconnect tool to release the fuel lines. Have a drain pan ready to catch any spilled fuel.

Step 4: Remove the Old Pump Module
Mark the module’s orientation with a marker so the new one goes in the same position. Use a fuel pump lock ring tool to loosen and remove the lock ring. Carefully lift the module out of the tank. Be gentle with the float arm to avoid bending it.

Step 5: Install the New Pump Module
Place the new pump module into the tank, ensuring the float arm moves freely and is not bent. Install a new tank seal O-ring. Tighten the lock ring to 35 to 40 foot-pounds using a torque wrench. Reconnect all fuel lines and the electrical connector.

Step 6: Test the System
Reconnect the negative battery cable. Cycle the ignition key 3 to 4 times without starting the engine to prime the fuel system. Check for leaks at all connections. Start the engine and verify the fuel pressure is within specification. Listen for unusual noises and monitor engine performance.

Important Technical Service Bulletin: Connector Replacement

Before installing your new fuel pump, be aware of a critical Technical Service Bulletin (TSB) from Stellantis. Bulletin 08-152-23 states that when replacing the fuel pump module on 2011-2016 Dodge Chargers, the fuel pump connector harness (pigtail) must also be replaced.

The updated fuel pump kits come with a revised harness connector that has different pin locations compared to the original. The new connector positions the fuel pump ground and fuel level sensor signals differently. If you do not replace the connector, the new pump may not function correctly, causing a crank/no-start condition.

The TSB applies to several part numbers, including 05136022AI, 68102700AB, 68103913AC, and 68145815AB. When you purchase your replacement pump, verify whether it includes the updated connector. If not, order the pigtail separately and follow the installation instructions provided with the kit.

Maintenance Tips to Extend Fuel Pump Life

Once you have installed your new fuel pump, follow these practices to maximize its lifespan:

Keep the Tank Above Quarter Full
Running the tank low forces the fuel pump to work harder and can cause it to suck up sediment from the bottom of the tank. The fuel in the tank also helps cool the pump. Maintaining at least a quarter tank reduces heat buildup and extends pump life.

Use Top Tier Fuel
Quality fuel contains detergents that keep the fuel system clean. Cheap, low-quality fuel can leave deposits that clog the fuel filter and strain the pump. Top Tier certified fuels meet higher standards for cleanliness.

Replace the Fuel Filter
While the 2015 Charger’s fuel filter is integrated into the pump module, the filter can still become clogged over time. If your mileage exceeds 60,000 miles, consider replacing the filter as part of your maintenance routine.

Consider Fuel System Cleaners
Periodically using a quality fuel system cleaner can help remove deposits from injectors and other components. Follow the manufacturer’s instructions carefully. However, do not rely on cleaners as a substitute for proper maintenance.

Diagnostic Tips Before Replacing

Before spending money on a new fuel pump, perform these simple checks to confirm the pump is actually the problem:

Listen for Priming Sound
Turn the ignition key to the ON position without starting the engine. You should hear a brief buzzing sound from the rear of the car for 1 to 2 seconds. If you hear nothing, check the fuel pump relay and fuse first. A blown fuse or faulty relay is much cheaper to fix than a pump replacement.

Test Fuel Pressure
Connect a fuel pressure gauge to the service port on the fuel rail. With the engine running, the pressure should read between 58 and 62 PSI. If the pressure is low or fluctuates wildly, the pump is likely failing. If the pressure is normal but you still have symptoms, the problem may be elsewhere in the fuel system.

Check for Other Causes
Hard starting and stalling can also be caused by a clogged fuel filter, faulty fuel pressure regulator, dirty injectors, or sensor problems. A scan tool can help identify whether the issue is fuel-related or caused by another system.
