Detailed Description

Built for diesel fuel filtration service, the Baldwin BF1348-SP helps separate water from fuel before it reaches sensitive injection components. The filter uses an integral post seal and a 1/2-20 sensor port thread, and Baldwin notes that OP8752 may be used to plug the sensor port when required. This part cross-references Racor S3225P for the same application. It is a direct-fit service part for Blue Bird Buses, Freightliner trucks, Hino trucks, Peterbilt trucks, and Racor 325 Series applications where the listed dimensions and thread specifications match.

What It Helps Address

  • Water contamination in diesel fuel
  • Restricted fuel flow from a loaded separator element
  • Seal leakage at the filter head
  • Sensor port service needs on compatible fuel systems
  • Replacement needs for Racor S3225P applications

Installation Notes and Tips

Verify thread size, height, outside diameter, and sensor port requirements before installation. Use the included gasket and O-ring during service, and confirm the sensor port is addressed correctly if your system does not use a sensor. Match the BF1348-SP to the existing filter head and housing design on Blue Bird Buses, Freightliner, Hino, Peterbilt, or Racor 325 Series equipment.

Quality Assurance

Baldwin manufactures filtration components for heavy-duty diesel service with published dimensional and connection specifications to support accurate part matching. The BF1348-SP is identified by Baldwin part number BF1348-SP for straightforward catalog and service verification.
