In the world of heavy machinery maintenance, precision is everything. The FL11-50 (also searched as FL1150) is a critical component for ensuring the longevity of your fuel system. Whether you are performing a routine service or a complete engine overhaul, using an OEM-standard filter prevents contaminants from reaching high-pressure injectors.
Our FL11-50 fuel filters are designed for high-efficiency separation of water and particles, specifically tailored for Cummins B Series and Komatsu 102/107 series engines used in excavators, loaders, and power generators.

Choosing the right supplier for engine parts like the FL11-50 is about balancing cost and reliability. Below is a comparison between our OEM-standard replacements and generic market alternatives.
| Key Purchase Factor | Our OEM-Standard FL11-50 | Generic Aftermarket Filters |
|---|---|---|
| 1. Filtration Efficiency | 99% retention of particles > 5 microns | Inconsistent, often allows bypass |
| 2. Material Quality | High-grade synthetic media + metal housing | Cheap paper media, prone to collapse |
| 3. Sealing Tech | High-temp resistant rubber gaskets | Low-grade seals prone to fuel leaks |
| 4. Service Life | Full 500-hour maintenance interval | Frequent clogging before scheduled service |
| 5. Fitment Accuracy | Exact dimensions for PC200/PC220 series | Loose threads or difficult installation |
| 6. Equipment Warranty | Maintains engine warranty compliance | Risk of voiding warranty due to failure |

Q: Why is my engine losing power when under load?
A: This is often caused by a clogged fuel filter like the FL11-50. If the filter media is saturated with debris, the fuel flow to the pump is restricted, leading to "starvation" and power loss. Replace the FL1150 immediately to avoid damage to the injection pump.
Q: How do I handle water-in-fuel warnings on Komatsu S6D107 engines?
A: The FL11-50 serves as a primary barrier. If the warning persists, check the bowl at the bottom of the filter. If water levels are high, drain it or replace the filter element if it has reached its capacity.
Q: Why Choose This Product?
A: Our FL11-50 features an OEM-standard tri-metal structure and high-performance synthetic media. It is trusted by repair shops & equipment fleets worldwide for its reliability in harsh construction environments.
