Fuel Filter with 25 Micron Rating

This spin-on fuel filter separates water from fuel and carries a 25 micron rating for fine particle capture. It is built for diesel systems that require a 1-14 thread connection and a sensor port for monitoring. The integral post seal and O-ring are included to simplify installation. It suits fleets and owner-operators who need reliable contamination control.

Capacity and Headroom

The filter handles typical commercial fuel flows while trapping contaminants down to 25 microns. Its height and outside diameter of 8-1/8 and 4-9/32 inches fit standard spin-on heads without modification. The unit will not suit applications that demand a finer micron rating or a different thread size. Systems needing higher flow capacity may require a larger housing.

Bundled Accessories and Software

The box supplies the filter with an integral post seal and an O-ring so no separate sealing parts are needed. A 9/16-18 sensor port is machined into the body for direct connection of a water-in-fuel sensor. No additional brackets, drain valves or electronic modules are provided. Installers must supply their own sensor and wiring.

Questions about this item

Will the 1-14 thread on this BF1330-SP fit the existing fuel line fittings on my older diesel engine?

The filter uses a 1 In. -14 thread size, so it matches any fuel line or housing with the same 1-14 specification. Verify your current fitting size before installation.

How can I confirm the 25 micron spin-on filter is sealing and draining correctly after I install it?

Prime the system, start the engine and check the integral post seal and O-ring for leaks. Open the drain to remove any collected water and ensure fuel flows clear.

Does the box include the sensor for the 9/16-18 port or do I need to buy that separately?

The filter includes the 9/16-18 sensor port, integral post seal and O-ring. The actual water-in-fuel sensor is not included and must be purchased separately.
