How to Match This Part

This aftermarket water-in-fuel sensor replaces Volvo Penta 3808616 (current) and the earlier number 874572. It threads into the bottom of the engine-mounted fuel filter and signals water contamination in the diesel fuel.

Match this part in this order:
1. OEM number — 3808616 or 874572 on the sensor, filter, or parts list
2. Engine family — Volvo Penta D3, D4, or D6 diesel
3. Location — sensor in the base of the engine-mounted fuel filter

Confirm the number on the original sensor before ordering. This listing is the filter-base water sensor, not a tank-level sender.

Installation Guide

1

Stop the engine. Disconnect the battery. Work with a drip tray — residual diesel will drain from the filter base.

2

Unplug the sensor connector. Unscrew the original sensor from the bottom of the engine-mounted fuel filter. Compare the OEM number to 3808616 or 874572.

3

Clean the filter-base seat. Fit a serviceable sealing washer if the service manual calls for one. Thread the new sensor in by hand, then snug it. Do not overtighten.

4

Reconnect the harness and battery. Start the engine and confirm the water-in-fuel warning behaves normally. Drain water from the filter if the alarm remains on.

Note: Professional installation is recommended to ensure safety and optimal performance.
