Detailed Description

WIX engineered the 33311 to deliver dependable filtration across a wide range of GM passenger cars and vans. The filter media is selected for the fuel type and application, helping maintain cleaner fuel flow while supporting engine protection in daily use. With its complete in-line design, this fuel filter is suited to vehicles that require a serviceable inline replacement rather than a cartridge-style element.

For shoppers searching for a fuel filter for 2000-2005 Buick LeSabre, a 1997-2005 Chevrolet Malibu fuel filter, or a 1992-2004 Pontiac Grand Am fuel filter, the WIX 33311 matches a broad set of OE cross-references and vehicle applications. This part cross-references FRAM G7315 and Purolator F54714 for the same application.

What It Helps Address

• Restricted fuel flow caused by contamination in the fuel line
• Fuel system wear from dirt and debris entering the engine supply
• Rough running related to a clogged inline fuel filter
• Service interval replacement needs on GM fuel filter applications
• Fuel delivery issues in stop-and-go or short-trip driving

Installation Notes and Tips

Verify inlet and outlet sizing before installation, and confirm the vehicle’s fuel filter location and line connection style against the application listing. Replace the filter at the OEM service interval or sooner if fuel contamination is suspected. After installation, check for leaks and confirm proper fuel pressure and engine operation.

Quality Assurance

WIX fuel filters are built with application-specific media and durable construction to support reliable filtration under normal and severe driving conditions. The 33311 is intended as an OEM-style service replacement for listed vehicles and fuel system configurations.
