Fuel/Water Seperator

The WIX RACING FILTERS Fuel/Water Separator (Model 33604) is a critical filtration component designed for diesel engines that demand maximum fuel purity and water removal. Whether you're running a high-performance Cummins inline-6 or maintaining fleet vehicles in wet climates, this separator protects your fuel injectors and combustion system from the corrosive effects of free and emulsified water. Fuel contamination is a silent killer—water in diesel fuel causes rust, deposits, and injector failure—making this separator an essential upgrade for serious engine builders and fleet operators who prioritize reliability over cost.

This canister-style separator uses an 8-micron media to trap particulate while its internal water-absorption design actively removes moisture before fuel reaches your engine. The steel construction and white powder-coat finish provide durability against harsh underhood environments and fuel system vibration. At 9.730 inches tall with a 1-14 inch NPT thread connection, the separator integrates seamlessly into existing fuel systems, offering 8.9-liter capacity between service intervals—sufficient for most light-duty and mid-range diesel applications. The robust engineering ensures consistent pressure drop and flow rate, critical factors in maintaining factory fuel delivery specifications.

Mechanics and diesel enthusiasts installing this separator on Cummins engines benefit from extended injector life and improved cold-start performance, especially in regions with high-moisture fuel supplies or older tank infrastructure. OEM manufacturers specify water separation for a reason—preventive fuel treatment costs far less than injector replacement or engine rework. Installation requires basic mechanical skill and a filter wrench; the 1-14 inch thread accommodates standard diesel filter canisters. For anyone operating diesel vehicles in demanding conditions or seeking to maximize engine longevity, this WIX RACING FILTERS component delivers proven protection and performance heritage.
