This is the Wix Filters 33619 fuel filter, a complete in-line OE replacement designed specifically for certain Volkswagen vehicles equipped with the 1.9L diesel engine made between 1997-2009. It filters fuel before it reaches the engine, protecting fuel injectors and pump from contaminants.
Constructed with cellulose media material that delivers a 23 micron nominal rating, this filter features 8 mm inlet/outlet ports and a precise outer diameter of 3.43 inches (top). It is a full-flow inline design ensuring compatibility with factory fuel line setups, and includes gaskets/outr-O-rings as required for sealing.
By trapping dirt, rust, scale, and water, it helps maintain consistent fuel flow, supports engine efficiency, and ensures long service life. Especially under diesel conditions, protecting the diesel fuel system from debris is critical to avoid misfires, reduced fuel economy, and potential fuel system damage.
