Mercury Quicksilver Carburetor Fuel Filter – Part No. 35-53336Q
This OEM carburetor inlet fuel filter (also listed as 53336Q) installs directly inside the carburetor fuel inlet fitting, capturing debris and contaminants before they reach the jets and needle valve. Replacing this small but critical strainer at regular service intervals helps maintain smooth throttle response and protects carburetor internals from premature wear.

Parts Desk Insights
Best use case: Annual preventive maintenance or any time the carburetor is removed for cleaning or rebuild. This filter is inexpensive insurance — a clogged strainer is a common cause of lean-running conditions and hard starting that gets misdiagnosed as a carburetor rebuild.
Common mistakes: Ordering this filter for EFI or MPI engines — those systems use an inline fuel filter, not a carburetor strainer. Also confirm your carburetor model: some 4.3L and 5.7L applications used different carburetor configurations across serial number ranges, and the inlet fitting size can vary.
Dimensions
- Small cylindrical strainer element — fits inside carburetor fuel inlet fitting
- Approximate weight: 50 g (0.05 kg)
