5023341 Water Separator Element — Cat 426F

This is a water separator element designed to remove water and larger contaminants from diesel fuel, protecting the injection system from damage. It meets high separation efficiency standards, providing cleaner fuel than a saturated or damaged element. A failed water separator can allow water into the engine, causing poor combustion, injector damage, and potential engine stalling.

Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a compromised water separator element is the illumination of a water-in-fuel warning light, or visible water in the collection bowl. If ignored, water can enter the fuel injection system, leading to rough engine operation and potential damage to injectors. Continued operation with water in the fuel can result in severe engine performance issues and costly repairs.

Installation Tip

Ensure the new element is properly seated in its housing to create a tight seal, preventing fuel bypass. Do not overtighten the housing cap, as this can crack the plastic or damage the O-ring seal.

Service Note

Inspect the fuel tank for any sediment or water accumulation and check the fuel lines for leaks when replacing the water separator element.
