The only maintenance necessary on an Alliance fuel/water separator is to replace the filter element.

Warning: Diesel fuel is flammable and can ignite if exposed to an open flame, intense heat, or other ignition source. Do not drain fuel near, or expose fuel vapor to open flame or intense heat. Exposure to open flame or intense heat could start a fire, possibly resulting in personal injury or property damage. When working on a fuel system, have a fire extinguisher within easy reach.

  1. Place a suitable drain pan under the fuel/water separator and open the drain valve. Drain enough fuel to empty the filter, then close the drain valve. See Fig..
