• Spin-on fuel/water separator filter for heavy-duty applications
• 9 micron cellulose media for fine contaminant capture
• 556 sq. in. filter area for extended dirt-holding capacity
• Corrosion-resistant can, center tube, and end caps
• Threaded 1-14 mounting thread with closed top design
• Drain cock included for water purging

Detailed Description

WIX 33968 is a heavy-duty fuel water separator filter engineered to remove water and contaminants from diesel fuel before they reach sensitive injection components. The enhanced cellulose media is paired with strong sealing components and a durable housing to support leak-resistant operation in commercial and industrial use. This part cross-references NAPA Gold Filters 3968 for the same application.

For buyers searching for a WIX 33968 fuel water separator filter, a 9 micron spin-on diesel filter, or a heavy-duty water separator with drain cock, this part is built around those requirements. It is also a relevant replacement search for Kohler GM41512 applications where this filter number is specified.

What It Helps Address

• Water contamination in diesel fuel
• Premature wear in fuel system components
• Restricted fuel flow from dirty fuel
• Injector issues caused by fine debris
• Service interruptions from separator maintenance needs

Installation Notes and Tips

Install the WIX 33968 as a spin-on fuel/water separator filter using the correct 1-14 thread specification and verify the sealing surfaces are clean before tightening. Use the drain cock to purge collected water during routine service, and confirm the replacement matches the required fuel system specification before installation.
