Fuel Water Separators

How to Compare Fuel Water Separator Replacements

A fuel water separator filter should be matched to the installed fuel system, not selected from appearance alone. Start with the complete part number, then confirm the filter position, head or housing, thread or element interface, gasket, bowl and drain arrangement, sensor or heater connection, dimensions, fuel type, and required flow and test evidence.

OXELR organises replacement references by part number so maintenance teams, distributors, and purchasing departments can compare the available catalog before requesting a quotation. If the exact reference is not listed, send the installed number, equipment or engine details, photographs, quantity, and delivery country for review.

What Should Be Matched Before Ordering?

Browse Current Fuel Water Separator References

The current catalog contains 26 fuel water separator and related separator references. Examples include the FS1015 spin-on fuel water separator reference and the BF7679D / RE61723 reference for the John Deere 540G application. Each product page is a starting point for technical comparison; final suitability should be checked against the installed system and approved documentation.

For standard diesel fuel-filter elements that do not include a water-separation function, browse the Fuel Filters category. Do not treat a fuel filter and a fuel water separator as interchangeable unless the equipment documentation identifies the required function and position.

Information to Include With a Fuel Water Separator RFQ

1. Installed filter manufacturer, complete part number, and suffix
2. Equipment and engine manufacturer, model, serial, and fuel-system position
3. Head or housing number and whether an assembly, element, bowl, or service kit is required
4. Thread, gasket, can or cartridge dimensions, bowl, drain, sensor, and heater details
5. Required flow, restriction limits, fuel specification, materials, and applicable test evidence
6. Quantity, sample or drawing requirement, packaging notes, and delivery country

Send the installed reference and RFQ details. Photographs of the label, sealing face, bowl, drain, sensor, and equipment nameplate are useful when a marking is incomplete.

Fuel Water Separator FAQ

Is a fuel water separator the same as a fuel filter?

Not always. A separator addresses undissolved water, while a fuel filter controls particles. Some assemblies combine both functions and some fuel systems use separate stages. Verify the installed unit's function and location.

Can I choose a replacement by thread size?

No. Thread size alone does not confirm the gasket seat, bowl or sensor interface, dimensions, fuel-system position, flow requirement, materials, or performance evidence.

Can the old bowl or water sensor be reused?

Only when the manufacturer identifies the exact combination as compatible and the component passes the required inspection. Confirm its interface, seal, material, and parent assembly.

What if the part number is unreadable?

Send equipment and engine identification, head or housing number, photographs, and controlled measurements. These details can support candidate identification, but they do not replace application and performance verification.
