Fuel filter or water separator?

A fuel filter is selected mainly by micron rating, flow capacity, sealing design and connection style. A water separator adds drainage or separation capability, so it must also be checked against water contamination risk, diesel storage quality and service interval.

Buyer checklist

  • Compare the installed filter label, OEM number and aftermarket reference number.
  • Confirm height, outside diameter, gasket, thread or end-cap structure.
  • Check whether the application needs a standard fuel filter, a water separator or a complete fuel filter kit.
  • Send photos, quantity, packing requirement and target market before sample approval.
Brand names and part numbers are used only for replacement identification and compatibility checking. They do not imply that GUOHAO is the trademark owner or an official catalog publisher for those brands.

For a quotation, send the current part number, photos of the installed filter, estimated quantity, packing requirement and target market to GUOHAO. This helps confirm samples before repeat OEM or private-label orders.
