Sierra 18-7976 Marine Fuel Filter with O-Rings, Crusader 23250 Cross Reference, Pack of 2

The Sierra 18-7976 is a marine fuel filter with O-rings, built to keep contaminants out of the fuel system on inboard engines. It is the direct cross reference for Crusader part number 23250, making it a straightforward replacement when the original filter is due for service. The filter body uses a metal outer housing for durability in the engine compartment environment, and it is finished in white.

This filter is sold as a package of 2, so boat owners servicing multiple engines or stocking a spare filter get both units in one purchase. It is a universal fit item, designed to work across compatible inboard fuel systems that use this filter and O-ring configuration rather than being limited to a single engine model. Each unit weighs 0.36 pounds and ships in compact packaging measuring 11.684 centimeters long by 5.588 centimeters high by 5.842 centimeters wide.

Routine replacement of the fuel filter is a standard part of marine engine maintenance, helping protect carburetors and fuel injection components from debris and moisture that can cause rough running or stalling. The included O-rings provide the seal needed at the filter housing to prevent fuel leaks and air intrusion once installed.
