What This O-Ring Does
The fuel filter bowl O-ring forms the primary seal between the removable fuel filter bowl and the fuel filter housing. Maintaining a proper seal helps prevent fuel leaks and keeps unwanted air from entering the fuel system.
Because fuel system seals are exposed to gasoline, ethanol blends, vibration, and age, replacement is recommended whenever the bowl is removed and the seal shows signs of wear.

Universal Marine Application
Sierra 18-7920 is a universal replacement fuel / water separator filter for compatible marine filter heads using a 1"-12 threaded filter.
Because this filter is used across multiple marine engine brands and fuel systems, fitment should be determined by the filter-head thread and the existing filter cross-reference number rather than by engine horsepower alone.
This is the large-hole 1"-12 thread style fuel / water separator.
Compare your existing filter number and filter-head thread before ordering. Marine fuel separator filters may look very similar while using different center-hole sizes or thread pitches.
What a Fuel / Water Separator Does
A marine fuel / water separator helps protect the engine fuel system by removing water and particulate contamination before the fuel reaches the engine.
Water can enter a marine fuel system through condensation, contaminated fuel or moisture in the tank. The separator provides an additional stage of filtration before the engine-mounted fuel filter or fuel injection system.
10-Micron Filtration
The Sierra 18-7920 is rated at 10 microns, allowing it to capture fine fuel contaminants while separating water from the fuel supply.
Maintaining a clean fuel / water separator can help reduce the chance of restricted fuel flow and contamination reaching carburetors, fuel pumps or fuel injection components.
When Should a Fuel / Water Separator Be Replaced?
Replacement intervals vary based on engine use, fuel quality and operating conditions. Fuel / water separator filters should be inspected and replaced as part of regular marine engine maintenance.
Replacement should also be considered whenever contaminated fuel or water in the fuel system is suspected.
Common Reasons for Replacement
- Routine annual or seasonal maintenance
- Water found in the fuel system
- Contaminated or stale fuel
- Restricted fuel flow
- Engine fuel starvation symptoms
- Unknown age of the existing fuel separator
- Replacing Fram CH33APL
- Replacing Johnson / Evinrude or OMC 771839
- Replacing Mercury 35-809099
- Replacing Racor B32014 or S3214
Installation Notes
Confirm that the filter head uses the correct 1"-12 thread before installation.
Follow the engine or filter-head manufacturer's installation procedure. Inspect the filter-head sealing surface and make sure the old filter gasket has been completely removed before installing the replacement.
