Development of a Fuel Filter and Water Separator for Diesel Engines 720777

A new fuel filter by Stanadyne is described. Its development, including shape and paper selection, is covered. The Master Filter makes use of unusual packaging concepts and techniques to overcome the ever-increasing problem of short filter life as diesel engine horsepower increases. Fuel filter paper evaluation, selection, and test results are described. Comparisons of, and arguments for, more realistic filter test methods are provided.
Supplementing the fuel filter is a new type of water separator using similar packaging concepts. This simple design provides very good capability for water removal at high flow rates. A water separator test method is outlined.
Both products offer contaminant visibility to encourage system maintenance.
