Donaldson Co Inc has announced a filter alliance agreement with Stanadyne Corp. In part, the alliance combines Donaldson's global market position with Stanadyne's modular diesel fuel filter system design and concept. Donaldson is now the primary marketer within North America and Europe for Stanadyne's large Fuel Manager 1000 Series diesel fuel filtration system that applies to large on-highway vehicles. Stanadyne's other Fuel Manager assemblies will be available through DCI throughout the world in non-North American or European nations.
