Fuel Filters
Our fuel filters provide clean, filtered fuel that prevents pump wear, injector clogging, premature engine wear and can boost fuel efficiency. Donaldson has a complete line of spin-on, and cartridge-style filters.

Primary Fuel Filters
This large capacity filter is positioned on the suction side of the pump. It removes water from the system before it gets to the pump.

Secondary Fuel Filters
Designed to endure higher pressures than the primary filter, a secondary filter is applied on the pressure side of the pump. It provides high efficiency particulate filtration and is required to remove emulsified water in some systems.
 

Fuel Filter/Water Separators
Our durable fuel filter/water separators trap contaminants carried in the fuel and strip away water that can damage your engine.
Donaldson Twist&Drain™
Donaldson Twist&Drain valve turns the messy and complicated task of draining water from the fuel filter into the easy process it should be.
 

Synteq for Fuel Filtration
Our newest filter media technology is our Synteq fuel media technology. This multiple-layered media technology is designed specifically to remove water AND contaminant from the fuel stream.
