In terms of compatibility verification, KEMSO achieves millimeter-level precision matching through 3D scanning technology. For Honda’s third-generation Earth Dream engine (such as L15B7), the flange mounting hole spacing of its Fuel Pump module is 72±0.1mm, and the tolerance with the original factory parts of the Civic from 2016 to 2022 is controlled within ±0.05mm. Laboratory vibration test data shows that under the working conditions of 20-200Hz frequency and 1.2g amplitude (simulating urban roads), the displacement of the KEMSO-TF1201 model connector is only 0.3mm, which is lower than the original factory safety threshold of 0.5mm, avoiding the risk of flameout caused by poor contact. According to the 2023 North American Honda Technical Bulletin, the fuel pressure fluctuation of the Civic modified vehicle using this pump body remained within ±1% during the 100,000-kilometer durability test.
The flow performance has been certified by Honda’s HDS diagnostic system. Real vehicle tests show that the KEMSO high-pressure pump core (internal code KHP-340) provides a flow rate of 255L/h at a working pressure of 350kPa, which is 23% higher than the original 2017 Accord 2.0T pump, meeting the 400-horsepower modification requirements. The NSX GT3 team reported that under continuous track conditions (oil temperature 90°C), the flow rate attenuation of this product is only 1/6 of that of the original factory parts (KEMSO: 1.5% attenuation after 500 hours vs. Honda original factory: 10% attenuation after 100 hours). Key parameters such as the response time of the pressure sensor being less than 8ms, which is faster than the original factory standard of 15ms, effectively preventing the sudden drop in fuel pressure during VTEC switching.

The material processing technology has enhanced the adaptability to extreme environments. The KEMSO pump body with a double-layer nickel-plated shell has withstood salt spray tests for more than 1000 hours (ISO 9227 standard), while the original Honda parts showed rust and perforation after 720 hours. Research after the 2022 Florida hurricane disaster showed that 300 Civic pumps equipped with this pump had a zero failure rate when wading through water to a depth of 40cm, thanks to the IP67 sealing design (two orders of magnitude higher than the original factory’s IP65 protection level). In high-temperature tests, the service life of PTFE sealing rings was extended to 8,000 hours in a 120°C fuel environment, which was 400% longer than that of nitrile rubber.
The economic benefit dimension significantly reduces user costs. KEMSO’s direct-mounted solution reduces installation time by 70% (with an average time consumption of 20 minutes) and saves 120 labor costs compared to general pump retrofitting. According to the sales data of 20 dealers, the retail price of the KM-E85Pro model equipped with an E85-compatible valve body (compatible with the 2023 Civic TypeRFL5) is 89.5 yuan, which is 36% lower than that of the original Honda parts. The 12-month return rate is only 0.8%, and the after-sales claim cost has decreased by 55%. In the 2024 Time Attack event, the 23 teams using this product saved over $150,000 in maintenance budgets due to zero fuel system failures.
Based on the comprehensive life cycle data, the direct-mounted pumps manufactured by KEMSO’s ISO/TS 16949-certified production line still maintained a flow accuracy of 98.7% after 30,000 start-stop tests (Honda’s standard is 95%), verifying the technical foresight and commercial rationality of its “plug and play” solution through a data loop.
