2015 Dodge Charger Fuel Pump: Complete Guide to Replacement, Symptoms, and Best Options
If you own a 2015 Dodge Charger and are experiencing starting problems, engine sputtering, or unusual noises from the fuel tank area, the fuel pump is likely failing and needs immediate attention. The 2015 Dodge Charger fuel pump is a critical component that delivers fuel from the tank to the engine at the correct pressure, and when it fails, your vehicle simply won't run properly. Based on extensive research and technical service bulletins, the most reliable solution is to replace the entire fuel pump module assembly rather than just the pump itself, and for optimal performance and longevity, the KEMSO brand offers the best value with lifetime warranty coverage.
Understanding Your 2015 Dodge Charger Fuel Pump System
The fuel pump on your 2015 Dodge Charger is not a simple standalone pump. It is part of an integrated fuel pump module assembly that sits inside the fuel tank. This module includes the electric fuel pump, the fuel level sending unit, the fuel pressure regulator, the fuel strainer, and the float mechanism that measures how much fuel is in your tank. When you replace the fuel pump, you are typically replacing the entire module assembly, which ensures all components work together seamlessly.
The 2015 Dodge Charger came with several engine options, including the 3.6L V6 Pentastar, the 5.7L HEMI V8, and the 6.4L SRT HEMI V8. All of these engines use similar fuel pump module designs, but the specific part numbers may vary depending on your engine size and whether your vehicle has the 18-gallon or 26-gallon fuel tank. The fuel pump operates at a pressure range of 58-62 PSI and delivers a flow rate of approximately 190 liters per hour, which is sufficient for even the most demanding HEMI engines.
Common Symptoms of a Failing Fuel Pump
Knowing the warning signs of a failing fuel pump can save you from being stranded on the side of the road. Here are the most common symptoms to watch for:
1. Engine Cranks But Won't Start. This is the most obvious sign. If your engine turns over but refuses to fire up, the fuel pump may not be delivering fuel to the engine. The technical service bulletin from Stellantis specifically addresses this issue, noting that technicians may experience a crank/no start condition after fuel pump replacement if the connector is not properly updated.
2. Engine Sputtering at High Speeds. If your Charger hesitates or loses power when you accelerate, especially at highway speeds, the fuel pump may not be maintaining consistent pressure. This occurs because the pump cannot keep up with the engine's fuel demand under load.
3. Whining Noise from the Fuel Tank. A healthy fuel pump operates quietly. If you hear a loud humming or whining sound coming from the rear of your vehicle, particularly near the fuel tank, the pump bearings may be wearing out. This noise often gets louder as the fuel level drops.
4. Sudden Stalling. Your engine may run fine for a while and then suddenly shut off without warning. This is dangerous, especially in traffic, and indicates that the fuel pump is intermittently failing.
5. Check Engine Light. The check engine light may illuminate with diagnostic trouble codes such as P0087 (fuel rail pressure too low) or P0230 (fuel pump circuit malfunction). These codes point directly to fuel delivery issues.
6. Poor Fuel Economy. If you notice that you are filling up more frequently than usual, the fuel pump may be working harder than necessary, causing the engine to run rich and waste fuel.
Why You Should Replace the Entire Module
Many vehicle owners make the mistake of trying to replace just the fuel pump motor inside the module. This is not recommended for several reasons. First, the fuel pump module is a sealed unit designed to be replaced as a complete assembly. Second, the sending unit that measures your fuel level is equally prone to failure, and replacing only the pump means you will likely need to drop the tank again when the sending unit fails. Third, the fuel strainer and other internal components wear out over time, and replacing the entire module ensures everything is fresh.
The 2015 Dodge Charger fuel pump module includes the fuel pump, sending unit, float, fuel reservoir, fuel strainer, and tank seal. This complete assembly ensures proper fuel delivery and accurate fuel level readings for years to come.
Step-by-Step Replacement Guide
Replacing the fuel pump on a 2015 Dodge Charger is an advanced DIY project that requires careful attention to safety. The estimated time for this job is 3 to 6 hours, depending on your experience level and whether your vehicle has an access panel under the rear seat.
Safety Precautions
Before starting any work, you must depressurize the fuel system. Fuel vapors are highly flammable, so work in a well-ventilated area, keep fire extinguishers nearby, and disconnect the negative battery cable before opening the fuel system. Wear safety glasses and nitrile gloves to protect yourself from fuel exposure.
Required Tools
You will need a floor jack and jack stands, a socket set from 8mm to 18mm, a torque wrench, fuel line quick-disconnect tools, a fuel pump lock ring tool, a brass punch and mallet, a drain pan, and shop towels. The brass punch is important because it will not create sparks when striking metal.
Accessing the Fuel Pump
There are two ways to access the fuel pump module. If your vehicle has a service cover under the rear seat, you can remove the rear seat cushion and access the module through that opening. This is the easier method. If there is no access cover, you must lower the fuel tank, which is significantly more labor-intensive.
To remove the rear seat cushion, use a flat trim tool to release the front clips, then lift the cushion out. Clean around the service cover thoroughly so no dirt falls into the fuel tank. Remove the cover fasteners using an 8mm or 10mm socket.
Disconnecting the Module
Unplug the electrical connector by hand, being careful not to break the locking tabs. Use needle-nose pliers only if necessary. Disconnect the fuel lines using the quick-disconnect tool set, and catch any spilled fuel in a drain pan. Mark the position of the module with a marker pen so the new one goes in the same orientation.
Removing the Old Module
Use the fuel pump lock ring tool to loosen the lock ring. If it is stuck, tap it gently with a brass punch and mallet. The brass prevents sparks. Once the lock ring is removed, lift the module out slowly, being careful not to bend the float arm or damage the tank. Set the old module aside on a shop towel.
Installing the New Module
Position the new fuel pump module assembly in the same orientation as the old one. Ensure the float arm is not bent and moves freely. Tighten the lock ring to 35-40 ft-lbs using the lock ring tool. Reconnect the fuel lines and electrical connectors. Make sure the O-ring seal is properly seated to prevent future leaks.
Priming the System
Reconnect the negative battery cable. Cycle the ignition key to the ON position three or four times without starting the engine. This allows the fuel pump to prime the system and build pressure. Check all connections for fuel leaks. Once you are confident there are no leaks, start the engine and let it idle. Inspect the area again for any signs of leakage.
Important Note About the Connector
According to the Stellantis Technical Service Bulletin 08-152-23, when replacing the fuel pump module on 2015 Dodge Charger models, you must also replace the fuel pump connector harness (pigtail). The updated fuel pump kits come with a revised harness connector that has different pin locations than the original. The old connector part numbers include 05136022AI and 68102700AB, while the new connector part numbers include 05136022AJ and 68102700AC.
The new fuel pump module kit includes an instruction sheet showing how to install the new connector. Even if your old connector looks fine, it must be replaced because the electrical terminals are in different positions. Failing to replace the connector can result in a no-start condition after installation.
OEM vs. Aftermarket Fuel Pumps
When choosing a replacement fuel pump for your 2015 Dodge Charger, you have two main options: OEM (Original Equipment Manufacturer) parts from Mopar or aftermarket alternatives.
OEM Mopar Fuel Pumps. Genuine Mopar fuel pumps are designed specifically for your Charger and meet the exact specifications required by the engine. The part numbers for the 2015 Dodge Charger fuel pump module include 68145815AF, 5136022AM, and 68102700AE, depending on your specific vehicle configuration. OEM pumps offer flow consistency within ±2% variance, corrosion-resistant stainless steel internals, and direct bolt-on fitment without modifications. They operate at approximately 50 dB, which is very quiet. However, OEM parts are typically more expensive, ranging from $300 to $450.
Aftermarket Fuel Pumps. Aftermarket options from brands like Delphi, Bosch, and Spectra Premium are available at lower price points, typically $120 to $250. However, these pumps often have flow consistency variances of ±15%, which can trigger lean codes. They may also be more prone to ethanol degradation and may require spacer adjustments for proper fitment. Noise levels are typically higher, around 65 dB or more.

Maintenance Tips to Extend Fuel Pump Life
Once you have installed your new fuel pump, follow these tips to maximize its lifespan:
1. Keep Your Tank Above 1/4 Full. The fuel in your tank helps cool the electric fuel pump. Running the tank low frequently causes the pump to run hotter, which accelerates wear. Make it a habit to refill when the gauge reaches 1/4 tank.
2. Replace the Fuel Filter Regularly. The fuel filter should be replaced every 60,000 miles to prevent debris from reaching the pump and causing premature failure.
3. Use Top Tier Fuel. High-quality fuels from reputable brands contain detergent additives that keep the fuel system clean. Avoid low-quality gasoline from discount stations, as it may contain higher levels of contaminants that can clog the fuel pump strainer.
4. Address Check Engine Lights Promptly. If your check engine light comes on with fuel system related codes, address the issue immediately rather than ignoring it. Small problems can escalate into complete pump failure.
5. Listen for Warning Signs. If you hear any unusual noises from the fuel tank area, investigate them immediately. Early detection of a failing pump can prevent you from being stranded.
