About This Part

Genuine Volvo Penta 24215091 is the current OEM spin-on fuel/water separating filter for selected later-generation D4 and D6 G-series marine diesel engines. It incorporates a sensor port in the filter base for the water-in-fuel detection system, which is a key difference from earlier D4/D6 filter generations. This filter removes water and fine contaminants from diesel fuel before they can reach the engine’s high-pressure common-rail injection system, where contamination can cause rapid injector wear or failure. Confirm engine model, serial number, and the existing filter part number before ordering — Volvo Penta used different filters across D4 and D6 production runs, and engines can look identical externally while requiring different filters.

Always confirm engine model, serial number, and existing filter configuration before ordering. The sensor port in the base of this filter is required for G-series engines equipped with the water-in-fuel detection system.

Service Interval

Replace at the fuel filter service interval specified in the Volvo Penta service schedule for your engine model. Also replace immediately if fuel contamination, restricted flow, excessive water accumulation in the filter bowl, or filter blockage is detected. D4 and D6 common-rail fuel systems operate at very high pressure — a clean primary fuel supply is essential to injector service life.

Installation Notes

Before installation, confirm the filter base sensor port matches your engine’s water-in-fuel sensor connection. Transfer or reinstall the water-in-fuel sensor as required by the Volvo Penta service procedure. Fill and bleed the fuel system following the applicable Volvo Penta service manual procedure. Inspect the filter sealing surface for damage before installation, and check carefully for fuel leaks after priming and starting the engine.

Parts Desk Insight

This filter is the most commonly confused item among D4 and D6 fuel system service parts. The G-series engines that use 24215091 look nearly identical to earlier D4/D6 models externally, but the water-in-fuel sensor port in the base of this filter is what distinguishes it. Fitting an earlier filter without the sensor port on a G-series engine will disable the water-in-fuel warning system. Match by engine serial number and existing filter number — not by engine displacement or output rating alone.
