Replacing Fuel Pump In 2008 Dodge Charger: Step-By-Step Guide

If your 2008 Dodge Charger is stalling or failing to start, you may need to replace the fuel pump. The fuel pump is located inside the fuel tank and ensures that pressurised gasoline flows to the engine to power the vehicle. While most fuel pumps will last for the life of the vehicle, they can occasionally fail or become weak, especially if the vehicle has been driven for over 100,000 miles or the tank has been run empty, causing the pump to overheat.

Signs of a failing fuel pump

The fuel pump in your 2008 Dodge Charger is designed to last the entire life of the vehicle, but sometimes it can fail. Here are some signs that indicate a failing fuel pump:

• Whining or whirring noise from the fuel tank – The fuel pump makes a low, barely audible humming sound when functioning normally. However, if you hear a loud whining or whirring noise coming from the fuel tank, it could be a sign that the pump is failing.
• Trouble starting the car – If the fuel pump is unable to deliver enough fuel to the engine, you may experience difficulty in starting the car. The car may crank but not start, or it may require more attempts than usual to turn over.
• Sputtering or stalling while driving – A faulty fuel pump may not be able to maintain the necessary fuel pressure, causing the engine to sputter or stall, especially when accelerating or driving uphill.
• Engine surges – If the fuel pump is malfunctioning, it can send too much fuel to the engine, resulting in speed spikes and drops even when you're not touching the gas pedal or the brake.
• Lower fuel efficiency – A failing fuel pump can allow excess fuel to enter the engine, leading to increased fuel consumption and more frequent trips to the gas station.
• Loss of power – If you notice a decrease in power when driving uphill or carrying heavy loads, it could be due to an inadequate fuel supply from a failing fuel pump.
• Engine overheating – An old or worn fuel pump can get too hot, causing the entire engine to overheat and stall.
• Check Engine light – If the fuel flow becomes restricted, the "Check Engine" light may illuminate.

If you notice any of these symptoms, it's recommended to consult a qualified technician or mechanic for a comprehensive inspection and diagnosis.

Where to find a fuel pump in a Dodge

The fuel pump in a Dodge Charger is located inside the fuel tank. Modern vehicles have electronic fuel injection systems, so the fuel pump is mounted inside the fuel tank. This is in contrast to older vehicles, which had mechanical fuel pumps that were often attached outside the fuel tank.

The fuel pump in a Dodge Charger can be accessed through an access panel in the passenger compartment or by removing the fuel tank from the vehicle. It is important to note that this is a moderately complicated job and is best performed by a trained mechanic or at a dealership's service department.

There are two types of fuel pumps in a Dodge Charger: the main fuel pump and the auxiliary fuel pump. The main fuel pump is located on the driver's side and is responsible for moving fuel to the engine. The auxiliary fuel pump is located on the passenger side and sends excess fuel back to the driver's side. Both pumps work independently and have their own fuel float.

When replacing the fuel pump, it is important to get the correct part for your vehicle's particular design, including tank depth, and whether you need the left module assembly or the auxiliary pump on the right side.

Fixing vs replacing a fuel pump

Fixing vs. replacing a fuel pump on a 2008 Dodge Charger depends on several factors. Firstly, it's important to identify the signs of a failing fuel pump, such as an engine that struggles to maintain speed, unusual noises, backfires, or a sputtering engine. If these issues are ignored, they can lead to engine overheating and eventual failure to start.

While it is technically possible to fix a fuel pump, it is generally recommended to replace it instead. Fuel pumps are designed to be long-lasting, but they can fail due to various reasons, such as normal wear and tear over time or running the fuel tank empty, which can cause the pump to overheat. Given the complexity of accessing the fuel pump, which is located inside the fuel tank, it is best to leave this task to professionals at a service center specializing in Dodge vehicles. They will have the necessary training and knowledge to diagnose the issue accurately and perform the required repairs or replacements.

When replacing the fuel pump, it is crucial to use a fuel pump specifically designed for your 2008 Dodge Charger, taking into account factors such as tank depth and whether you need the left module assembly or the auxiliary pump on the right side. The average national cost for a fuel pump replacement across all vehicles ranges from $611 to $894, including parts and labor, but the price may vary depending on your specific Dodge model and other factors.

To summarize, while fixing a fuel pump on a 2008 Dodge Charger may be an option for those with exceptional mechanical skills, it is generally more reliable and practical to replace the fuel pump with a model designed for your specific vehicle. This ensures the long-term reliability of your car and avoids the need for temporary fixes that may not address the root cause of the problem.

Symptoms of a bad fuel pump

The fuel pump in your 2008 Dodge Charger is responsible for delivering fuel from the tank to the engine at the correct pressure. When the fuel pump starts to fail, you may experience difficulty in starting the engine or even complete stalling. Other symptoms of a failing fuel pump include:

• Engine sputtering during acceleration, which occurs when the fuel pump cannot deliver a consistent fuel flow to the engine, causing interruptions in the combustion process.
• Hard starts or failure to start the engine, especially after the vehicle has been sitting for a while.
• Engine stalling, which can be dangerous as it leads to a sudden loss of power steering and brakes.
• Loss of engine power, resulting in sluggish acceleration and difficulty maintaining speed, particularly during uphill driving or when the car is fully occupied.
• The check engine light coming on, indicating a problem with the fuel delivery system.
• A whining noise from the fuel tank.
• Stumbling.

Ignoring these symptoms can lead to performance issues and even a complete breakdown. If you suspect your fuel pump is failing, it is best to have it inspected and repaired as soon as possible.

Fuel pump replacement cost

The fuel pump replacement cost for a 2008 Dodge Charger varies depending on the service provider and location. The average national cost for a fuel pump replacement across all vehicles is between $611 and $894, including parts and labor. However, the cost for a Dodge Charger specifically can be higher, ranging from $1,131 to $1,592. This range does not include taxes and fees and may differ based on your location.

When replacing the fuel pump, it is recommended to also replace the fuel filters and the fuel pump relay, as they are known to fail in some vehicles. Additionally, it is important to take all necessary precautions when working with the fuel system to avoid the risk of fire.

The fuel pump is located inside the fuel tank and has a small electric motor to ensure that pressurized gasoline flows to the engine. While fuel pumps typically last for the life of the vehicle, they can occasionally fail. Signs of a failing fuel pump include a car that won't start, a stalled engine, a slowly starving fuel flow, a "Check Engine" light, or a whirring sound coming from the fuel tank.
