2010 Challenger Fuel Pump: Complete Replacement Guide, Cost, and Symptoms

The bottom line up front: If you own a 2010 Dodge Challenger and need a fuel pump replacement, expect to pay between $260 and $1,250 depending on where you get the work done and which parts you choose . The fuel pump on your Challenger sits inside the fuel tank, located at the rear of the vehicle beneath the trunk area, and accessing it requires either dropping the fuel tank or removing an access panel . Most fuel pumps on this generation last between 100,000 and 150,000 miles, but when they fail, you cannot ignore the problem for long . This guide covers everything you need to know about the 2010 Challenger fuel pump, including how to spot failure early, what replacement costs, which part numbers fit your car, and how to choose the right replacement.

Which Fuel Pump Does Your 2010 Challenger Use?

The 2010 Dodge Challenger uses an electric in-tank fuel pump, which means the pump sits inside the fuel tank rather than outside the engine like older mechanical designs . This is a returnless fuel system, meaning the pump delivers pressurised fuel to the engine without a return line back to the tank . The system operates at roughly 40 to 60 PSI depending on engine load and driving conditions .

Your 2010 Challenger may have one or two fuel pump modules depending on which fuel tank size your car came with. The 18-gallon tank uses a single primary pump located on the left, driver's side of the fuel tank . The 19-gallon tank also uses a driver-side primary pump, but some configurations include an auxiliary pump module on the right side as well . If your car has the larger tank, the right-side module works as a transfer pump to move fuel across the saddle-shaped tank. Both sides are accessible after dropping the fuel tank.

The 2010 Challenger came with three engine options: the 3.5L V6, the 5.7L HEMI V8, and the 6.1L HEMI V8 in the SRT8 . All three use similar fuel pump assemblies, but you must verify compatibility because the pump module part numbers differ between the V6 and V8 engines . The 3.5L V6 cars use a pump assembly that fits the 18-gallon tank, while the 5.7L and 6.1L cars may use either tank size depending on how the car was ordered .

How Much Does a 2010 Challenger Fuel Pump Replacement Cost?

Fuel pump replacement costs for the 2010 Challenger vary widely based on who performs the work and whether you choose original equipment or aftermarket parts. Here is what real pricing data shows:

Independent shop pricing from actual quotes:

  • A 2010 Challenger 3.5L V6 SE with 138,630 miles received a quote of $388 to $474 for fuel pump replacement
  • A 2009 Challenger 5.7L V8 R/T received quotes between $260 and $337

Dealer and general repair range:

  • Kelley Blue Book shows a fair repair range of $922 to $1,252 for the 2010 Challenger near Irving, Texas, with parts costing roughly $566 to $626 and labor at a similar amount
  • Independent shops tend to charge less, with the same repair coming in at $922 to $1,038

Parts-only costs:

  • Aftermarket fuel pump assemblies for the 2010 Challenger typically run between $67.95 and $115 for the driver-side primary pump
  • OEM Mopar fuel pump module assemblies cost more, with the left primary module listed around $409 to $443 and the right auxiliary module around $311
  • Used fuel pump assemblies from salvage yards list between $30 and $730, with a median asking price around $125

If you do the work yourself, the total cost comes down to just the price of the pump assembly plus a new lock ring and seal, which adds roughly another $54 if you buy Mopar parts . If you hire an independent mechanic, labour typically adds $145 to $600 depending on how many hours the job takes at standard shop rates . Dealership labour pushes the total toward the higher end of the range.

Symptoms of a Failing Fuel Pump in Your 2010 Challenger

Catching fuel pump failure early saves you from getting stranded and avoids potential damage to other fuel system components. Watch for these warning signs:

1. Engine stalls or struggles to start

A failing pump cannot maintain the pressure needed to keep the engine running. The car may crank but take longer to fire, or it may start and then stall shortly after . If the pump has completely failed, the engine will not start at all.

2. Loss of power under acceleration

When you press the throttle and the car hesitates, stumbles, or feels like it is not getting enough fuel, the pump is likely struggling to deliver adequate pressure . This often feels like the engine is "choking" or struggling to maintain speed .

3. Loud whining noise from the fuel tank

A healthy fuel pump is nearly silent. If you hear a buzzing, whining, or whirring sound coming from the rear of the car around the fuel tank, the pump motor is likely wearing out . The noise may be more noticeable on cold starts.

4. Engine overheating or check engine light

A fuel pump that runs hot can cause the engine to overheat because the pump relies on fuel flowing through it for cooling . You may also see the check engine light come on as the engine runs lean from low fuel pressure .

5. Sudden acceleration problems

If the car sputters, backfires, or hesitates during acceleration, especially when the tank is low, this points to the pump struggling to pick up fuel . Low fuel levels cause the pump to work harder and overheat.

If you notice any of these symptoms, stop driving the car and have the fuel pressure tested. Continuing to drive on a failing pump can clog the fuel injectors with debris or eventually cause the pump to seize completely.

Where Is the Fuel Pump Located?

The 2010 Challenger fuel pump sits inside the fuel tank, which is mounted in the rear of the car beneath the trunk area . You cannot simply open the trunk and reach it. Replacement requires either lifting the car and dropping the fuel tank or removing an access panel in the passenger compartment, depending on how the car was manufactured .

Here is what the access procedure generally looks like:

1. Safely raise the vehicle on jack stands and disconnect the negative battery terminal to prevent any electrical shocks .

2. Relieve fuel system pressure by locating the Schrader valve on the fuel rail and using a suitable tool to depressurise the system .

3. Remove the fuel tank shield and disconnect the electrical connectors and fuel lines from the tank .

4. Lower the tank slowly and carefully. The fuel pump module sits on top of the tank and is secured by a locking ring .

5. Use a specialised tool to release the locking ring, then carefully lift the pump module out of the tank .

The job requires intermediate mechanical skill and proper safety equipment like gloves and safety goggles because you are working around gasoline . If you have any doubt about your ability to complete this repair safely, have a shop handle it.

Replacement Part Numbers for the 2010 Challenger

Ordering the correct fuel pump is critical. Using the wrong part can cause poor fuel pressure, a fuel leak, or a check engine light. Here are the part numbers that fit the 2010 Challenger:

OEM Mopar part numbers:

  • Left side primary fuel pump module: 68102700AE or 68102700AC
  • Left side primary fuel pump module (older revision): 05136022AM
  • Right side auxiliary fuel pump module: 05136023AF
  • Lock ring: 52110282AA
  • Fuel pump and level unit o-ring kit: 68304753AA

Aftermarket interchangeable part numbers:

  • E7241M fits the 18-gallon driver-side tank on 2009-2010 Challenger models with the 3.5L V6 and 5.7L V8 engines
  • Delphi DFG1052 fits the left side on 2010 Challenger 3.5L V6 models with the 18-gallon tank
  • Other interchangeable numbers include 5136021AE, 5136021AF, 5136021AG, 5136021AD, RL136021AG, and 04578218AD

Aftermarket brands that make direct replacements:

  • Autopart Premium makes a right-side fuel pump assembly for the 2008-2014 Challenger with the pressure sensor and sending unit included
  • Replacement brand offers a right-side fuel pump assembly with the pressure sensor and wiring harness for the same years
  • MAYCCI makes the E7241M direct replacement for the 18-gallon tank driver-side position

Always verify the part number against your specific VIN and tank size before ordering. If you have the 19-gallon tank, you may need both the left primary pump and the right auxiliary pump .

3 Things To Check Before Buying a Replacement Fuel Pump

1. Confirm the fuel tank size

Measure your tank or check your window sticker. The 18-gallon tank uses a different pump module than the 19-gallon tank . If you have the larger tank, you need to confirm whether your car has the auxillary right-side pump .

2. Verify engine size and VIN

The 3.5L V6 and the 5.7L V8 use different part numbers even though the installation process is similar . The 6.1L SRT8 also has specific fitment requirements . Check your engine code and VIN before ordering.

3. Decide between OEM and aftermarket

OEM Mopar parts cost more but guarantee proper fit and use the same materials as the factory pump . Aftermarket pumps like the E7241M offer lower prices and direct-fit installation . Both options work, but be sure to choose a brand with a warranty and a solid return policy.

What Is a Fuel Pump Module Assembly?

When you shop for a replacement, you will see terms like "fuel pump assembly," "fuel pump module," and "sending unit." Understanding what these mean helps you avoid ordering the wrong part.

A fuel pump module assembly is the complete unit that drops into the fuel tank. It includes the electric pump itself, the fuel level sending unit that powers your gas gauge, and often a pressure sensor and wiring harness . Some kits also include the strainer, o-ring, and float .

1. Fuel pump - The electric motor that pushes fuel through the lines to the engine. This is the core component that fails.

2. Fuel sending unit - A float-operated resistor that tells your dashboard gauge how much fuel is left in the tank . If this fails, your fuel gauge will read empty or move erratically even when the tank is full.

3. Pressure sensor - Some Challenger modules include a sensor that monitors fuel pressure inside the tank and reports it to the engine computer . This helps the PCM regulate pump speed for the returnless fuel system.

4. Strainer or filter - A mesh sock on the intake side of the pump catches dirt and debris before they enter the fuel system . It should be replaced whenever the pump is replaced.

If you buy a complete module assembly, you get all these parts in one unit, making installation straightforward .

How Long Should a 2010 Challenger Fuel Pump Last?

Most fuel pumps on this generation last roughly 100,000 to 150,000 miles under normal driving conditions . However, several factors can shorten that lifespan:

1. Running the car on a low tank regularly. The pump uses the fuel around it for lubrication and cooling. When the tank is near empty, the pump runs hotter and can overheat .

2. Fuel contamination. Dirt, rust, or water in the tank damages the pump over time. The strainer catches larger debris but fine particles eventually wear down the pump motor.

3. Clogged filters. If the fuel filter is not replaced at regular intervals, back pressure builds up and forces the pump to work harder than it should, burning it out sooner.

If you drive your Challenger hard, tow, or live in a hot climate, expect the pump to fail closer to the lower end of that range.

Can You Replace the Fuel Pump Yourself?

Replacing the fuel pump on a 2010 Challenger is a moderately difficult repair that most home mechanics can complete with the right tools and a service manual . The process takes roughly 2 to 4 hours if you have experience lifting vehicles and handling fuel system components. If you have never worked on a fuel tank before, this job carries real risk because a mistake can lead to a gasoline leak or an electrical short.

Tools you will need:

  • Jack stands and a floor jack to lift the car
  • Fuel line quick disconnect tool
  • Lock ring removal socket or a flat-head punch and mallet
  • Socket set and torque wrench for reinstalling
  • Gloves and safety goggles

Key precautions:

  • Always disconnect the negative battery terminal before starting
  • Relieve fuel pressure before loosening any fuel line
  • Work in a well-ventilated area away from open flames or sparks
  • Replace the o-ring and lock ring whenever they are removed

If this sounds beyond your comfort level, the total cost of professional installation may still be the smarter choice, especially if you factor in the risk of fuel leaks or damage to the tank.

Choosing the Right Brand: OEM vs. Aftermarket Fuel Pumps

You have three basic options when it comes to replacing your 2010 Challenger fuel pump:

1. OEM Mopar
These are the exact same parts installed at the factory. They cost more, but you get guaranteed fitment and durability. The left primary module lists around $409 to $443 for the module alone . If you want to keep your Challenger all original, this is the safest route.

2. Major aftermarket brands
Companies like Delphi, Bosch, and Autopart Premium manufacture fuel pumps that meet or exceed OEM specifications. Delphi has been a Tier 1 supplier to global automakers for over 80 years and holds more than 150 patents in fuel technologies . These pumps typically cost less than OEM while delivering similar performance .

3. Economical direct replacements
Brands like MAYCCI make direct-fit modules such as the E7241M that match the original part number interchange . The Choice brand and others offer modules for under $100 . These are budget-friendly options, though warranty coverage varies, so check carefully before buying.

Independent repair shops commonly use aftermarket parts, which is why their labour quotes often run lower than dealer pricing . The trade-off is that you must trust the shop to select a quality brand, so do your research ahead of time.
