Helpful Comparison Insights

When choosing the best fuel pumps for FiTech systems, you’ll notice a few key distinctions. Flow rate (LPH) is paramount; a 255 LPH pump like the FiTech Inline is great for stock to moderately modified engines, while the 340 LPH units, whether in-tank or part of a Force Fuel system, are better suited for higher horsepower applications. The EVIL ENERGY 300 LPH pump also fits into this performance category with added fuel compatibility.

Another critical decision is in-tank versus inline/external. In-tank pumps (FiTech In-Tank 255Lph or 340Lph) are generally quieter and run cooler, extending their lifespan, but they demand more complex installation involving tank modification. Inline pumps (FiTech Inline 255Lph, EVIL ENERGY External 300LPH) are easier to install externally, typically along the frame, but can be louder and more exposed.

For those wanting to avoid tank modifications entirely, the FiTech Master Fuel Delivery Kit (which includes an inline pump) or the Fitech Force Fuel system are fantastic. The Force Fuel system, with its dual 340 LPH pumps, is specifically designed to convert low-pressure stock tank fuel into a high-pressure EFI supply, making it an ideal solution for classic cars. Meanwhile, accessories like the FiTech Fuel Pump Mounting Bracket, while not a pump itself, are crucial for securely installing any inline pump. Consider your power goals, budget, and willingness to modify your fuel tank to guide your decision.

Final Verdict

Deciding on the absolute best FiTech fuel pump really comes down to your specific build and priorities.

If you’re after a no-fuss, comprehensive solution that handles everything for a frame-mounted inline setup, the FI-TECH Master Fuel Delivery Kit Inline Frame Mount is your go-to. It simplifies the entire fuel delivery aspect, perfect for a smooth EFI conversion.

For the performance enthusiast with a built engine who values stealth and quiet operation, the FI-TECH FUEL INJECTION In-Tank 340Lph EFI Fuel Pump delivers high flow and reliability tucked away in the tank. If your budget is tighter and horsepower needs are moderate, the FI-TECH FUEL INJECTION Inline 255Lph EFI Fuel Pump offers great value and easier external installation.

And for those high-horsepower, classic car builds where cutting the tank is a non-starter, the Fitech Force Fuel, Fuel Delivery System, Dual 340 LPH is the undisputed champion, offering serious flow and incredible convenience. Lastly, don’t forget the EVIL ENERGY External Inline Fuel Pump Electric 300LPH as a robust, versatile option, especially if you plan on running E85. Whichever you choose, ensure it aligns with your engine’s power requirements and your installation preferences to keep your FiTech system purring!

FAQ Section

Q1: Why is a special fuel pump needed for FiTech EFI systems?
A: FiTech EFI systems, like most modern electronic fuel injection, require significantly higher fuel pressure (typically 40-60 PSI) and a higher volume of fuel flow (LPH – Liters Per Hour) compared to traditional carbureted engines (which usually run on 5-9 PSI). A dedicated EFI fuel pump is essential to provide this consistent high pressure and flow for proper atomization and engine performance.

Q2: What’s the difference between an in-tank and an inline (external) fuel pump for FiTech?
A: An in-tank fuel pump is submerged inside your fuel tank. This typically makes it quieter, keeps it cooler (which can extend its lifespan), and reduces the risk of vapor lock. However, it requires modifying your fuel tank. An inline or external fuel pump is mounted outside the fuel tank, usually along the frame rail. These are generally easier to install as they don’t require tank modification but can be noisier and run hotter.

Q3: How do I know what LPH (Liters Per Hour) fuel pump I need for my FiTech system?
A: The required LPH depends on your engine’s horsepower. Generally, a 255 LPH fuel pump is suitable for engines up to around 500-600 horsepower. For higher horsepower applications (e.g., 600-800+ HP), a 340 LPH or even a dual-pump setup like the Fitech Force Fuel system becomes necessary. Always check FiTech’s recommendations for your specific EFI kit and engine output.

Q4: Can I use my original fuel tank with a FiTech system?
A: Yes, you can often use your original fuel tank. If you’re using an inline fuel pump (like the FI-TECH Master Fuel Delivery Kit or a standalone inline pump), you’ll need to run a new, larger fuel line from the tank to the pump, and a return line. Alternatively, systems like the Fitech Force Fuel are designed to work with your stock, low-pressure tank, transforming it into a high-pressure EFI-ready system without internal tank modifications.

Q5: What’s the “returnless” system often mentioned with FiTech fuel pumps?
A: Many FiTech systems, especially the “Force Fuel” setups, utilize a returnless fuel delivery design. This means the fuel pump module or regulator returns unused fuel to the tank at the pump module itself, rather than having a separate return line running all the way back from the engine bay. This simplifies plumbing, especially for classic car conversions, as you typically only need a single high-pressure feed line to the engine.

Q6: Is installing a FiTech fuel pump a difficult DIY task?
A: The difficulty varies. Installing an inline fuel pump with a robust mounting bracket can be a moderately easy DIY task for someone with basic mechanical skills, as it mainly involves running new fuel lines and wiring. Installing an in-tank fuel pump, however, is more involved as it requires dropping the fuel tank, potentially cutting or modifying it, and sealing it properly. Always ensure you have the right tools and follow safety precautions when working with fuel.
