If you’re driving a Dodge Neon SRT-4, you already know it’s not your average compact car. With its turbocharged 2.4-liter engine and sport-tuned performance, this vehicle thrives on precision—especially when it comes to parts like the fuel pump. Whether you’re upgrading for more power or replacing a worn-out unit, choosing the right fuel pump ensures your ride stays reliable and responsive.
Let’s start by understanding why the fuel pump matters. The SRT-4’s engine relies on a steady flow of fuel to maintain its turbocharged performance. A failing pump can lead to sputtering, loss of power, or even engine stalling—issues you definitely want to avoid. The stock fuel pump in the Neon SRT-4 is designed for factory specs, but if you’ve modified your engine (like adding a bigger turbo or tuning for higher boost), you’ll need an upgrade to keep up with increased fuel demands.
So, which fuel pump fits the Dodge Neon SRT-4? The direct replacement for the OEM pump is the **Walbro 255lph in-tank fuel pump** (model number GSS342). This high-flow pump is a popular choice because it supports up to 450 horsepower, making it ideal for mild to moderately tuned SRT-4 builds. It’s a drop-in replacement, meaning installation is straightforward if you’re familiar with working on fuel systems. But if you’re pushing beyond 450 HP, consider a dual-pump setup or a larger aftermarket unit like the **DW300** to ensure adequate fuel delivery.
Now, here’s where things get interesting. Not all fuel pumps are created equal. Cheap, off-brand pumps might save you money upfront, but they often fail prematurely or struggle to maintain consistent pressure under high load. That’s why sticking with trusted brands like Walbro, AEM, or Bosch is crucial. For example, the Fuel Pump from Kemso Racing is another solid option tailored for high-performance applications. It’s designed to handle aggressive driving conditions while providing the durability needed for daily use.
Installing a new fuel pump in your Neon SRT-4 isn’t overly complicated, but it does require patience. You’ll need to drop the fuel tank, which involves safely disconnecting the battery, relieving fuel pressure, and supporting the tank as you remove it. Always replace the fuel filter and inspect the tank for debris while you’re in there. If you’re not confident tackling this yourself, a trusted mechanic can get it done in a few hours.
One common question is whether upgrading the fuel pump alone will boost performance. The answer? It depends. If your current pump is failing, a new one will restore lost power. But if you’re chasing horsepower gains, a higher-flow pump needs to be paired with other mods—like larger injectors, a tuned ECU, or a stronger turbo—to see real results. Think of the fuel pump as part of a system; it’s a supporting player that enables other upgrades to shine.
Maintenance is another key factor. Fuel pumps can last 100,000 miles or more, but contaminants in low-quality gas or running the tank consistently near empty can shorten their lifespan. Using a fuel additive occasionally and sticking to reputable gas stations helps keep the pump (and your engine) healthy.
In summary, the Dodge Neon SRT-4 thrives with a fuel pump that matches its spirited nature. Whether you stick with a Walbro 255lph for reliability or opt for a performance-focused unit like Kemso Racing’s, prioritize quality and compatibility. Remember, a well-chosen fuel pump doesn’t just keep your car running—it ensures every drive lives up to the SRT-4’s legacy of speed and excitement.
(Note: Always consult a professional or factory service manual for installation guidance, and double-check compatibility with your specific model year before purchasing.)
