FM100 Series
The FM100 Series is designed for diesel engines with a fuel flow rate up to 80 US gallons/hr (300 liters/hr). Typical engines range from 50 to 350 HP. The FM 100 Series consists of a cast aluminum mounting header, with a choice of threaded ports of almost any configuration up to M16 x 1.5 'O' ring in size. "Push-in" quick fit connectors can also be specified, making fuel line connections easy, quick, and less costly. The filter elements interface with the header using a patented "Key Track" system, which, like the FM 10 Series, is designed to ensure that only the correct, genuine service element can be installed on the header.
Stanadyne Fuel Manager Diesel Fuel Filter & Water Separator

Fuel Manager is a unique, patented, modular diesel fuel filter/water separator system that can be customized for virtually any application.

Fuel Manager is designed for use in truck, automotive, heavy equipment, marine, industrial and agricultural diesels. The completely modular system has interchangeable components that can be added or removed easily and independently.

All Fuel Manager units remove both particulates and water, and can be adapted for a variety of applications. Optional modular features can be added by the manufacturer, dealer, and in most cases the user. 

Each employ Stanadyne's unique filtration process, trapping more impurities and water without impeding the flow rate. The product's design permits the replacement of elements without the use of tools and without spilling fuel, making service easy in the shop or in the field. When an element is replaced, an easily opened drain valve allows the filter to be completely and neatly emptied before it is removed.


A selection of modular options allows the system to be easily customized:

  • In-unit heater. (*Note - Heater will heat fuel to 45 F and shut off.  This heater is not designed for use with SVO or WVO alternative fuels) 
  • Electronic "water-in-fuel" indicator.
  • See-thru engineered plastic bowl for convenient visual inspection of water.
  • Hand primer.
  • Electric lift pump
  • Filter change indicator.
  • Special marine components are also available with extra anticorrosion protection.

The Fuel Manager's specially designed mounting header accepts any combination of these options. The Series also is available in "top-load" models, which make all serviceable parts accessible from above, providing greater flexibility in design for the OEM by reducing the need for surrounding work space.

Today, over 60 OEMs specify Stanadyne's Fuel Manager fuel filter/water separator systems for their engines and /or equipment. In addition, hundreds of other manufacturers, who use diesel engines made by John Deere, Caterpillar, Perkins, Sisu, Case, New Holland, Ford, and others are benefiting from the superior performance, flexibility, ease of use and competitive cost of Stanadyne's Fuel Manager systems.
