Good To Know
Q: What is the micron rating of the FS1251 filter? A: The filter media captures particles down to 10 microns while also separating free water. This level of filtration protects sensitive fuel injectors from abrasive contaminants.
Q: Will the FS1251 filter work as a direct replacement for the BF1226? A: Yes, the FS1251 is designed with the same thread size, gasket diameter, and flow rate as the BF1226. Always verify the filter housing and O-ring condition during the swap.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
