Cummins Fuel Filter FF236 1492513 High-efficiency filtering of oil circuit impurities Original replacement

This Cummins FF236 fuel filter as OEM replacement features targeted material improvements — the filter media uses high-density synthetic fiber with about 15% higher ash-holding capacity than OEM; better filtration of rust and gunk in the fuel line; extends injector life. OEM 1492513; fits Cummins ISX/ISM series and some Deutz engines. Function is to filter impurities in fuel to protect high-pressure pumps and common-rail; installation requires a special wrench to remove the filter housing; be sure to vent air from the filter before starting, or else risk dry-running of high-pressure pump.
