Fuel filters are paper replacement type and can be found screwing into carburetor fuel inlet or in fuel line. Ensure engine is cold, sat for at least 3 hours. Collect necessary tools, including appropriate replacement filter, wrenches for flare nut fittings on carburetor-mounted filters, or screwdriver and pliers for in-line types. Have clean rags ready to catch spilled fuel. Remove air cleaner assembly, note positions of vacuum hoses if disconnected. Follow fuel hose from fuel pump to locate filter. For carburetor-mounted filters, use wrench to hold nut, loosen fitting, and disconnect fuel line. Move line for better access, unscrew fuel inlet filter nut, and replace filter, gasket, and spring. Hand-tighten fuel inlet fitting into carburetor, then fully tighten using two wrenches. For screw-in type carburetor filters, remove clamps, hose, and filter, then hand-start new filter and fully tighten. Cut new fuel hose, position spring clamps, and attach to filter and steel fuel supply line. For in-line filters, remove clamps and hoses, cut new hoses, install clamps, and attach to filter, metal supply line, and carburetor inlet fitting. After installation, run engine, check for leaks, and reinstall air cleaner assembly, reconnecting hoses to original positions.

The fuel filter is located on the inside of the left-side frame rail.

To replace a carburetor inlet fuel filter, first, detach the line leading to the inlet. Carefully unscrew the carburetor inlet filter unit from the carburetor. To reinstall, thread a new filter into the carburetor and tighten it securely.

For screw-in type carburetor filters, remove clamps, hose, and filter, then hand-start the new filter and fully tighten. Cut a new fuel hose, position spring clamps, and attach to the filter and steel fuel supply line.

Before replacing the fuel filter on fuel-injected models, you should inspect the hose fittings for cleanliness and relieve the fuel system pressure.

The fuel filter is located under the vehicle on the inside of either the left or right frame rail, near the fuel tank.

Carefully push each hose onto the filter until it's seated against the collar on the fitting, then install the hairpin clips. Make sure the clips are securely attached to the hose fittings to prevent potential fuel leaks and fire hazards.

On models with the filter mounted on the outside of the carburetor, you'll need to loosen the screw clamp, disconnect the rubber hose, unscrew the fitting, and detach the filter.

Remove the hairpin clips from each fitting before detaching the fuel hoses from the filter.

Remove the filter-to-fuel line retainer clips if equipped. Then, remove the fuel lines from the filter.

Fuel filters in carbureted models should be replaced according to the maintenance interval suggestions and when a blockage in the fuel line occurs due to excessive foreign material in the fuel.
