Description
The Fleetguard FS19683 is a 10-micron spin-on fuel/water separator that replaces Caterpillar 175-2949 and Baldwin BF1268 on a wide range of Cat 3100, 3300, 3400, 3500, and C-series engines. Stratapore media delivers up to 95% free water separation and a built-in drain makes routine service quick — fits the standard 1-14 UNS-2B Cat fuel head.
