Fuel Filtration Details

WIX builds this filter with application-specific media and durable construction to support normal and severe driving conditions such as stop-and-go traffic, short trips, dirt roads, construction sites, and interstate travel. The 20 micron rating helps capture fine contaminants before they reach the fuel system, while the compact inline style supports straightforward replacement in many older carbureted and fuel delivery setups. This part number 33003 is also cross-referenced by MicroGard 33003 for the same application.

Installation Notes and Tips

Confirm 3/8 inch inlet and outlet sizing before installation and match the inline layout to the existing fuel line routing. The closed-top, complete in-line design is suited to direct replacement in many classic Pontiac, Jeep Wagoneer, and Lincoln Continental fuel systems. Always verify the vehicle’s fuel line condition and replace any damaged hose or clamps during service.
