Replacement Procedure
Danger:Remove the fuel pump fuse or relay before disconnecting any fuel line. The mechanical pump will continue to pump if the engine cranks — depressurizing prevents fuel spray. Work away from any ignition sources. Have a rag and drain pan ready.
- Remove the fuel pump fuse from the fuse box to depressurize the fuel system.
- Locate the in-line fuel filter. It sits in the engine bay inline between the fuel tank supply line and the carburetor.
- Place a rag under the filter to catch residual fuel. Use hose clamp pliers to slide the clamps back on both hoses, then pull each hose off the filter fittings.
- Note the flow direction arrow on the filter body before removing. Install the new filter with the arrow pointing toward the carburetor.
- Push both hoses fully onto the new filter fittings and slide the clamps into position over the fittings. Verify both clamps are fully seated.
- Reinstall the fuel pump fuse. Crank the engine a few times to build fuel pressure, then start it and inspect the connections for leaks.
Tip:Avoid generic filters for this application — stick to WIX 33310 or NAPA 3310. Dimensional mismatches with generic filters are common and a loose hose fit on a fuel line is a fire hazard.
Rubber Fuel Hose Replacement
The factory service manual specifies that all rubber fuel hoses must be replaced at a maximum of every 4 years, regardless of appearance. Rubber degrades internally from fuel contact before cracking is visible externally. Do not re-use a fuel hose once it has been removed.
Warning:On vehicles approaching or past the 4-year hose interval, inspect the hoses during every fuel filter change. Squeeze each hose — if it feels stiff, crumbly, or has surface cracking, replace it before it fails. A cracked fuel hose spraying onto a hot exhaust manifold is a fire that starts before you can stop it.
