Unleash the Full Potential of Your Dodge Charger: A Comprehensive Guide to Upgrading to a High-Performance Fuel Pump
Why Upgrade Your Fuel Pump?
When it comes to unlocking the true potential of your Dodge Charger, particularly the SRT Hellcat or other high-performance variants, one of the most critical components to consider upgrading is the fuel pump. The stock fuel pump, while adequate for standard driving, often becomes a bottleneck when you start pushing your car to its limits.
“Upgrading the fuel pump is one of the first steps in preparing your car for serious performance enhancements,” says John, a seasoned mechanic at 797 Performance. “It ensures that your engine is getting the fuel it needs to deliver that extra horsepower and torque.”

Understanding Your Current Fuel System
Before diving into the upgrade process, it’s essential to understand how your current fuel system works. The fuel system in your Dodge Charger is designed to provide the necessary fuel flow to the engine under various driving conditions. However, when you modify your engine with performance parts such as a cold air intake, exhaust system, or even a turbocharger, the stock fuel pump may not be able to keep up with the increased demand.
Here are some key components of your current fuel system:

- Fuel Tank: This is where the fuel is stored.
- Fuel Pump: Located inside the fuel tank, it pumps fuel to the engine.
- Fuel Filter: Ensures that the fuel is clean and free from contaminants.
- Fuel Injectors: Spray fuel into the engine’s combustion chamber.
- Fuel Pressure Regulator: Maintains the optimal fuel pressure.
Choosing the Right High-Performance Fuel Pump
When selecting a high-performance fuel pump, several factors need to be considered:
Flow Rate
The flow rate of the fuel pump is measured in liters per hour (LPH). For high-performance applications, you’ll need a pump that can deliver significantly more fuel than the stock pump. For example, the HHP Racing Plug & Play Dual Pump Walbro 525LPH Fuel System is designed for Dodge Charger SRT Hellcat models and can support up to 1600 BHP on gas and 1100 BHP on ethanol fuels[1].
Compatibility
Ensure the fuel pump is compatible with your vehicle. For instance, the Fore Innovations Hellcat Fuel Hat Assembly is specifically modified for returnless operation on 2015+ Dodge Charger and Challenger SRT Hellcat models[1].
Additional Components
A comprehensive upgrade kit should include all necessary components such as wiring harnesses, fuses, relays, and a fuel pump variable pressure controller.
Installation Process
Upgrading your fuel pump is not a trivial task, but with the right tools and instructions, it can be done effectively. Here’s a step-by-step guide to help you through the process:
Preparation
- Clean the Fuel Tank: It’s crucial to clean the fuel tank before replacing the fuel pump to avoid any contaminants causing the new pump to fail[2].
- Gather All Components: Ensure you have all the parts included in the upgrade kit.
Installation Steps
- Drain the Fuel Tank: Partially drain the fuel tank to minimize fuel spillage.
- Remove the Old Pump: Disconnect the electrical connections and fuel lines, then remove the old fuel pump.
- Install the New Pump: Mount the new fuel pump and connect the electrical connections and fuel lines.
- Install Additional Components: Install the new wiring harness, fuses, relays, and fuel pump variable pressure controller.
- Test the System: Start the engine and check for any leaks or issues.
Here is a detailed list of steps for the HHP Racing Plug & Play Dual Pump Walbro 525LPH Fuel System:
