Q: How to replace the fuel filter in Mercury Lynx?
A: The fuel filter can be accessed by removing the air cleaner housing situated on the top of the carburetor for the models fitted with a carburetor. Holding the filter hex with a back-up wrench, unscrew the line. Apply thread lock and sealer to the filter threads, hand screw it into the carburetor, and tighten it using a wrench. Hand-threaded into the filter, motor oil is applied to fuel line fitting threads before being tightened securely. The air cleaner housing should then be reinstalled. For fuel-injected models, relieve fuel system pressure and locate the fuel filter in the rear right corner of your engine compartment. Put hairpin clips on hose fittings, remove them, and plug both ends of each clip off. Check hairpin clips for damage, note the arrow on the filter for direction, loosen the clamp screw then detach the filter from the bracket.
