Sierra 18-7968 Fuel Water Separator Filter, 10 Micron, Replaces Mercury 35-18458Q4, V6 EFI 1996-Up

The Sierra 18-7968 is a 10 micron fuel water separator filter built for V6 EFI outboard engines from 1996-Up that use the sensor (blue) style fuel filter head. It removes water and particulate contamination from fuel before it reaches the engine, protecting fuel injectors and internal components from moisture damage and debris. The filter features a metal outer housing for durability in a marine environment and is manufactured to meet or exceed the quality of the original equipment part it replaces.

This filter is a direct replacement for the Mercury 35-18458Q4 and 35-184585 fuel water separator filters, and is also listed as interchangeable with the Mallory 9-37806 filter. It is designed to work with fuel filter heads equipped with a water-in-fuel sensor, matching the blue sensor-style configuration used on applicable V6 EFI Mercury outboards. Boat owners replacing a worn or clogged fuel filter on a compatible Mercury V6 EFI outboard can install the 18-7968 as a like-for-like swap without modification.
