2012 Dodge Charger Fuel Pump Location: Where It Is and How to Reach It
The bottom line up front: The fuel pump on a 2012 Dodge Charger is mounted inside the fuel tank, which sits beneath the rear of the car behind the rear seat area. You will not find it under the hood, and you cannot see it from outside the vehicle. To access it, you must either drop the fuel tank from underneath or, in some cases, cut an access hole through the trunk floor. Most 2012 models built before a certain date have a round access plate under the rear seat cushion on the driver side, but this is not guaranteed across all build dates and trims .
Unlike older vehicles where a mechanical pump bolted to the engine block did the job, the 2012 Charger uses an electric, in-tank fuel pump module. That module combines the pump, the fuel level sending unit, the strainer, and the pressure regulator into a single sealed assembly. That is why most owners and mechanics refer to it as a "fuel pump module" rather than just a fuel pump .
Understanding where the pump sits and how to reach it matters because the diagnostic process is different from what you might expect. If your Charger cranks but will not start, or sputters under load, the first step is to verify fuel pressure at the rail, not to start pulling the rear seat apart. Proper diagnosis can save you money because the symptoms you are seeing might come from a clogged fuel filter, a bad relay, or a wiring issue, not the pump itself .
The Exact Location Details
The 2012 Dodge Charger uses a saddle-style fuel tank. That means the tank wraps around the driveshaft, with two main chambers connected by a crossover section. The fuel pump module is mounted in the driver-side half of the tank in most configurations .
This is a critical detail: you cannot access the pump by simply lifting the rear seat on every model. You have two reliable ways to confirm the exact position on your specific car :
-
Check the driver-side rear area under the vehicle. With the car safely supported on jack stands, look above the rear axle on the driver side. You will see the plastic fuel tank shield, and behind it, the metal tank. The electrical connector and fuel lines route toward the driver side of the tank in most 2011–2014 Charger models .
-
Look for the access panel. Some early 2011 models built before a certain date do have a round access plate under the rear seat cushion on the driver side. A small number of vehicles from that model year still used the older "under-seat" access style inherited from the previous generation. If you lift the rear seat bottom (just pull up on the front edge and it pops free), check for a circular metal cover plate with three or four screws. If you see it, the pump is underneath. If you see only smooth floor pan, yours does not have the seat access design .
The safest way to verify which configuration you own is to enter your VIN on the dealer's parts lookup system. The parts catalog will list the correct pump module and the correct installation procedure for your build date .
Why the Access Method Matters
There are two accepted ways to reach the fuel pump on a 2012 Charger, and each has pros and cons you should weigh before starting. Neither method is "wrong," but one may be far more practical for your situation.
Method 1: Dropping the Fuel Tank (The Standard Shop Procedure)
This is what most professional shops do and what Chrysler's service manual recommends for most configurations. It involves the following steps :
- Disconnect the negative battery cable.
- Remove the fuel filler cap to relieve tank pressure.
- Use a fuel pressure gauge to confirm zero pressure at the rail before touching anything else.
- Raise the vehicle on a lift or support it securely with jack stands on all four corners.
- Remove the exhaust heat shields near the tank, which can sometimes require removing the rear section of the exhaust system entirely.
- Disconnect the fuel lines using the quick-connect tool. The lines are under the driver-side floor area.
- Disconnect the electrical connector for the fuel pump.
- Support the tank with a transmission jack or a purpose-built tank jack.
- Remove the two metal straps holding the tank in place.
- Lower the tank carefully, watching for the fuel fill hose and the vent hose.
Once the tank is down, remove the lock ring (a large metal or plastic ring) that holds the pump module in place. A hammer and a brass punch or a special lock-ring tool work well here. Lift the pump module out, noting the orientation of the float arm before you remove it .
The entire job takes 3 to 5 hours for a DIY owner working carefully in a garage. If you have never dropped a fuel tank before, expect it to take a full afternoon, not the "one-hour job" some forum threads claim .
Method 2: Cutting an Access Hole in the Trunk Floor
This is a popular workaround for owners who do not want to deal with tank removal, especially on cars with heavily rusted straps. However, it must be done with care because you are modifying the structure of the car .
The trunk floor on the 2012 Charger does not come with a factory access panel in most trims. To access the pump from above, you cut a rectangular or round hole in the floor pan directly above the pump location. The key issue: you must position the hole precisely or you will .
Symptoms of a Failing Fuel Pump
If your fuel pump is going bad, you will likely notice one or more of these warning signs. Acting quickly can prevent you from being stranded and avoid costly damage to other engine components :
-
Engine Sputtering or Stalling – If your Charger's engine sputters at high speeds or stalls unexpectedly, the fuel pump may not be delivering a consistent flow of fuel to the engine. This happens because the pump is unable to maintain steady pressure, causing the engine to hesitate or cut out for brief periods. Stalling is often followed by the engine restarting after several minutes, which is a classic sign of low fuel pressure .
-
Difficulty Starting the Engine – A bad fuel pump can cause long cranking times or prevent the engine from starting altogether. When you turn the key to the "ON" position, you should hear a brief buzzing or whirring sound from the fuel tank area as the pump primes the system. If you don't hear this sound, it could indicate the pump is not working .
-
Loss of Power During Acceleration – A properly functioning fuel pump must deliver more fuel when you step on the gas pedal. If the pump is failing, it cannot keep up with the engine's increased demand, resulting in a noticeable loss of power when accelerating or climbing hills. This power loss is usually temporary at first but becomes more severe as the pump deteriorates .
-
Decreased Fuel Efficiency – When the fuel pump cannot maintain proper pressure, the engine may run rich or lean, both of which reduce fuel economy. If you notice your gas mileage dropping significantly without any other obvious cause, a failing fuel pump could be to blame .
-
Whining Noise from the Fuel Tank – A loud, high-pitched whining noise coming from the fuel tank area is often one of the first signs of a failing fuel pump. While all fuel pumps make some noise during operation, an unusually loud or high-pitched whine indicates the pump is working harder than normal and may be near failure .
What Causes Fuel Pump Failure
Understanding why fuel pumps fail can help you prevent problems and extend the life of your replacement pump.
Wear and Tear. Like any mechanical component, fuel pump internal parts degrade over time. Continuous operation under high temperatures and pressures gradually diminishes the pump's components, leading to reduced efficiency and eventual failure. Fuel pumps typically last between 100,000 and 150,000 miles, but this varies based on driving habits and fuel quality .
Contaminated Fuel. Dirt, debris, and rust particles inside the fuel tank can obstruct the fuel pump, forcing it to work harder and ultimately leading to failure. Contaminated fuel may enter the tank during refueling or from deteriorating parts inside the tank itself. These contaminants can clog the fuel filter and pump, diminishing fuel flow to the engine and causing the pump to overheat .
Running the Tank Low on Fuel. Consistently running your Charger with less than a quarter tank of gas can shorten fuel pump life. The fuel inside the tank acts as a coolant for the pump, and running low means less cooling. Additionally, debris that settles at the bottom of the tank is more likely to be sucked into the pump when fuel levels are low .
Electrical Issues. Faulty electrical connections can lead to fuel pump failure. Damaged wiring, loose connections, or malfunctioning relays can disrupt power delivery, resulting in intermittent operation or complete pump failure. Regularly checking and maintaining the vehicle's electrical system, including the battery, can mitigate these risks .
Fuel System Leaks. Leaks within the fuel system can impact the fuel pump's performance. Damaged fuel lines, loose connections, or cracks in the fuel tank cause pressure loss, forcing the pump to work harder to maintain adequate fuel delivery .
How the Fuel Pump Works
The fuel pump is the heart of your vehicle's fuel delivery system. Its primary job is to draw fuel from the gas tank and deliver it to the engine at the correct pressure. In modern vehicles with electronic fuel injection (EFI), the pump must maintain consistent pressure so that when the fuel injectors open, the right amount of gasoline sprays into the intake manifold or engine cylinders .
Electric in-tank fuel pumps use an electric motor to drive an impeller or turbine. This creates pressure in the fuel lines, pushing pressurized fuel to the fuel injection system. The pump must provide a constant flow under the correct pressure to ensure the engine runs smoothly across all driving conditions, from idling to full throttle .
When you turn the ignition key, the engine control unit (ECU) activates the fuel pump relay, sending power to the electric motor inside the pump. The motor spins an impeller or turbine at high speed, creating suction that draws fuel through a strainer into the pump chamber. The spinning action pressurizes the fuel, which then exits through a check valve and travels through the fuel lines toward the engine. Within two to three seconds of turning the ignition, the system builds to operating fuel pressure, preparing the engine for start .
Modern gasoline engines typically require fuel pressure between 40 and 60 psi . The pump also includes a check valve that maintains residual pressure in the fuel lines when the engine is off, which reduces startup time and prevents fuel from draining back into the tank .
How Much Does Replacement Cost?
Depending on your Charger's model year and engine type, replacement costs typically range from $500 to $1,500, with the pump module itself costing between $150 and $500 and labor adding $350 to $1,000 or more .
Preventive Maintenance Tips
Preventive maintenance is the best way to extend the life of your fuel pump. Here are two essential tips :
-
Never let your fuel level drop below a quarter of a tank. The fuel in the tank helps cool and lubricate the pump. Running the tank low causes the pump to work harder and run hotter, which can shorten its lifespan dramatically. Lack of gasoline can kill a fuel pump in a matter of minutes .
-
Replace your fuel filter every 20,000 to 40,000 miles. A clogged fuel filter forces the pump to work harder to push fuel through to the engine. This added strain accelerates wear and can lead to premature pump failure. Replacing the filter on schedule is one of the cheapest and most effective ways to protect your fuel pump .
