Perkins 5578106 Pre-Fuel Filter Assembly – With 4395038 Filter & Sensor

The Perkins 5578106 fuel filter assembly is supplied as a complete unit, including the 4395038 pre-fuel filter, filter head, bowl, and water sensor. It’s designed to protect Perkins engines by removing water and dirt from the fuel before it reaches the injection system.

From our experience, this assembly is one of those parts where using genuine makes a big difference. The clear plastic bowl and integrated sensor make it easy to spot water contamination early, which helps prevent injector damage and costly downtime. Aftermarket versions sometimes fit loosely or the sensors fail quickly, but the 5578106 unit bolts straight on and works reliably. If you’re maintaining a Perkins-powered machine, this filter assembly saves time and gives peace of mind.
