NOTE: The FS1251 water separator filter is an upgraded version of the Fleetguard FS1235 fuel filter. This diesel fuel water separator filter is designed for use with the Cummins 3311505S filter head.
The water separator filter is a spin engine spin-on type filter that removes both free and coarse water down to a 20 Micron level. The Fleetguard FS1251 Water Separator Filter meets today's high-pressure fuel systems requirements for entrained and emulsified water separation that causes injector tips to wear out prematurely. Installation is simple and will be leak-free because replacement seals are included with this Filter. This Water Separator is a direct OEM Cummins replacement filter.
KLM recommends regularly draining this fleetguard fuel water separator filter to remove the water contained within this filter. Periodically removing the water from this Fleetguard water separator filter will help to prevent freeze-ups in your vehicle fuel system during the winter months. KLM Performance recommends keeping a spare set of the Fleetguard Replacement Filters in your vehicle at all times.
The Fleetguard Replacement Spin-On Fuel Water Separator Filter is MADE IN THE USA!
