Engine Protection Built for Harsh Australian Conditions

Protect your diesel fuel system from expensive damage with the Donaldson Diesel Pre-Filter Kit. This high-quality pre-filter removes water, rust, and fine contaminantsbefore they reach your factory fuel filter.

Modern common-rail diesel engines operate at extreme pressures (up to 3,100 bar / 45,000 psi). Even small amounts of water or dirt can destroy injectors or high-pressure fuel pumps — repairs that often cost thousands of dollars. This pre-filter adds an essential first line of defence.

Frequently Asked Questions

Does this replace the factory fuel filter?
No. It installs before the OEM filter, working in series for maximum protection.

Will it restrict fuel flow?

Can it be used with a ProVent 200 catch can?
