4. Fuel Pump Assembly Replacement SP8030M for 1998 1999 2000… (A ABIGAIL)

This A ABIGAIL fuel pump assembly is presented as a high-quality, direct OEM replacement. However, it’s crucial to note its listed application specifically mentions Honda Accord, Acura TL, and CL models. While it might share some similarities with other Honda fuel pumps, it is not a direct fit for the Honda S2000.

• User feedback summary: Users with compatible vehicles praise its ease of installation as a direct replacement and report restored fuel pressure and smooth engine operation. They often highlight the complete kit as a significant advantage, saving time and hassle. However, S2000 owners should look elsewhere.

5. SouthMarine 16700-ZT3-013 16700-ZT3-003 7387129 Fuel Pump…

They praise its ability to bring old equipment back to life. However, its lack of applicability for cars is evident from its reviews.

6. Electric Fuel Pump Compatible with Honda Civic del Sol…

This electric fuel pump offers broad compatibility across many Honda models, including a specific mention for the Honda S2000 (00-09), which is great news. It provides a flow rate of 191 Liters per Hour (LPH) and a pressure range of 90-105 psi, making it a viable option for a stock or lightly modified S2000. This pump is designed to be a direct replacement for many OEM units, meaning installation should be relatively straightforward. If you’re looking for a reliable, OEM-equivalent replacement that covers your S2K, this could be a strong candidate.

For S2000 owners, it’s seen as a solid replacement for a failing stock pump, providing adequate fuel delivery for daily driving and light spirited use. The included kit makes the swap process easier for many.

7. Genuine Honda Fuel Pump Assembly – 16700-ZT3-013

This product is listed as a “Genuine Honda Fuel Pump Assembly – 16700-ZT3-013.” While the allure of “Genuine Honda” parts is strong, it’s critical to clarify that the part number 16700-ZT3-013 is actually for Honda small engines and utility equipment, such as generators or lawnmowers (as seen with the SouthMarine review). This is NOT a fuel pump for the Honda S2000 automotive engine. Purchasing this for your S2000 would be a mistake, as it will not fit, nor will it provide the necessary fuel flow or pressure for your car. It’s a high-quality OEM part, but for a completely different application.

• Key Features:
  • Genuine Honda part.
  • Part number: 16700-ZT3-013.
• Pros:
  • Authentic Honda OEM quality for its intended small engine applications.

  • NOT for the Honda S2000.
  • Incorrect application could lead to frustration and potential damage if someone tried to force it.
  • Provides no direct benefit for S2000 owners.
• Best for: Owners of Honda small engines, generators, or lawnmowers seeking an authentic OEM replacement fuel pump. Absolutely NOT for the Honda S2000.

Helpful Comparison Insights

When you’re looking for the best fuel pump for your Honda S2000, it’s important to differentiate between direct OEM replacements for stock applications and high-performance upgrades for modified engines.

For those running a stock or lightly modified S2000, the Electric Fuel Pump Compatible with Honda Civic del Sol… (191 LPH) is a solid and affordable option, as it explicitly lists S2000 compatibility and offers OEM-like flow. It’s a straightforward replacement for a failing stock pump, getting you back on the road without breaking the bank.

If your S2000 has moderate performance upgrades, like bolt-ons, higher compression, or even a mild supercharger kit, the DeatschWerks Fuel Pump (255 LPH) is likely your sweet spot. It offers a significant flow increase over stock and, crucially, comes with a specific S2000 installation kit, making it much easier to install than more generic performance pumps. It strikes a great balance between performance and ease of fitment.

For the serious S2000 enthusiast pushing big power, especially with forced induction (turbo/supercharger) or planning to run E85, the KEMSO 340LPH High Performance Fuel Pumps (both listed versions) are the clear winners. Their ability to support up to 600 BHP and E85 compatibility makes them ideal. While the product name mentions “Accord,” their specifications are what matter for high-performance S2000s. Just be prepared for potential minor modifications during installation, as they aren’t explicit drop-in kits for the S2000. However, the lifetime warranty and USA-based support add significant value and peace of mind.

Now, a word of caution on the other pumps. The A ABIGAIL Fuel Pump Assembly (SP8030M) and both the SouthMarine 16700-ZT3-013 and Genuine Honda Fuel Pump Assembly – 16700-ZT3-013 are NOT suitable for the Honda S2000. These are designed for other Honda vehicles (Accord/Acura TL/CL) or small utility engines (lawnmowers, generators). Using them in an S2000 would either be impossible without extreme modification or severely detrimental to your engine’s health. Always double-check part numbers and applications, especially when buying online, to ensure you’re getting the right part for your specific model.

In summary, decide on your power goals first. Stock/mild needs: look for OEM replacements like the Electric Fuel Pump. Moderate power: DeatschWerks is a great balance. High horsepower/E85: KEMSO 340LPH is the way to go.

Final Verdict

Choosing the right fuel pump for your Honda S2000 boils down to your car’s current setup and your future performance aspirations. There’s no single “best” pump for everyone, but there’s definitely a best fit for your specific needs.

For the vast majority of S2000 owners who are running a stock engine or very light modifications and just need a reliable, cost-effective replacement, the Electric Fuel Pump Compatible with Honda Civic del Sol… is probably your best bet. It’s affordable, explicitly compatible, and provides adequate flow for daily driving and spirited runs.

If you’re in that sweet spot of moderate modifications, perhaps with an intake, exhaust, or even a supercharger running low boost, the DeatschWerks Fuel Pump (255 LPH) stands out. Its S2000-specific kit makes installation less of a headache, and its flow rate offers plenty of headroom without being overkill. This is a solid, reliable upgrade that most S2K owners will be happy with.

However, if you’re truly pushing the limits with a high-horsepower build, big boost, or plan to run E85 fuel, then one of the KEMSO 340LPH High Performance Fuel Pumps is your champion. These pumps are designed for serious power and come with an unbeatable lifetime warranty. Just remember to factor in potential minor fitment work, as they’re performance-oriented rather than direct S2000 drop-ins.

And for those wondering, let me reiterate: avoid the A ABIGAIL, SouthMarine, and the Genuine Honda 16700-ZT3-013 pumps for your S2000. These are simply not for our beloved roadsters and would cause more harm than good. Stick to the pumps that are genuinely designed for or adaptable to the S2000’s performance demands. Happy motoring!

FAQ Section

Q1: Why is a high-performance fuel pump important for my Honda S2000?
A: A high-performance fuel pump ensures your engine gets enough fuel, especially under high RPMs, heavy load, or when you’ve added modifications like forced induction (turbo/supercharger) or higher compression. The stock Honda S2000 fuel pump might not be able to keep up, leading to lean conditions, loss of power, or even severe engine damage. It’s a crucial component for both reliability and performance.

Q2: What’s the difference between LPH ratings (e.g., 191 LPH vs. 340 LPH)?
A: LPH stands for Liters Per Hour, which is a measure of the fuel pump’s flow rate. A higher LPH rating means the pump can move more fuel. A 191 LPH pump is generally suitable for stock or mildly tuned Honda S2000 engines, while a 255 LPH pump offers more headroom for moderate modifications. A 340 LPH pump is designed for high-horsepower builds, especially those running forced induction or alternative fuels like E85, which require significantly more fuel.

Q3: Is E85 compatibility important for a Honda S2000 fuel pump?
A: E85 (ethanol-based fuel) is popular in performance circles because it has a higher octane rating and a cooling effect, allowing for more aggressive tuning and power. However, E85 is corrosive to certain fuel system components. If you plan to run E85 in your Honda S2000, you absolutely need a fuel pump (and other fuel system parts) specifically designed to be E85 compatible to prevent premature pump failure and fuel system damage.

Q4: Can I install a fuel pump myself in my Honda S2000?
A: Fuel pump installation in a Honda S2000 is a moderately challenging DIY task. It typically involves accessing the fuel tank, disconnecting fuel lines, and working with electrical connections. While some pumps (especially those with “kits”) are more straightforward, others might require minor modifications or adaptations. If you’re comfortable working on cars and have the right tools, it’s doable. However, if you’re unsure, it’s always best to consult a professional mechanic, as improper installation can lead to fuel leaks or operational issues.

Q5: What are the signs that my Honda S2000 fuel pump is failing?
A: Common signs of a failing Honda S2000 fuel pump include:
* Difficulty starting the engine (especially when warm).
* Engine sputtering or cutting out at high RPMs or under heavy acceleration.
* Noticeable loss of power or sluggish acceleration.
* Whining noise coming from the fuel tank area.
* Engine running lean (can be detected with a wideband O2 sensor).
If you notice any of these symptoms, it’s wise to get your fuel system checked.

Q6: Why are some fuel pumps listed for other Honda models also recommended for the S2000?
A: Sometimes, a fuel pump’s generic specifications (like flow rate, pressure, and general size) make it suitable for a wide range of Honda engines, even if its product name mentions a different model like “Accord” or “Civic.” The key is to look at the LPH and pressure ratings, as well as features like E85 compatibility. However, if a pump specifically mentions an S2000 kit, that’s usually a bonus for easier installation. Always verify fitment and capabilities for your specific S2000 needs, especially for high-performance applications.

Q7: Do I need to upgrade other fuel system components with a high-flow fuel pump?
A: For truly high-horsepower Honda S2000 builds, just upgrading the fuel pump might not be enough. You might need to consider upgrading your fuel lines, fuel rail, fuel pressure regulator, and especially your fuel injectors to match the increased flow capacity. These components work together, and a bottleneck anywhere in the system can negate the benefits of a high-flow pump and potentially cause tuning issues. Consult with your tuner or a performance specialist for advice on a comprehensive fuel system upgrade path.
