The new pumps have several design changes which provide: * An improved knob to rod joint.* Improved torque retention.* Improved resistance to vibration induced wear.These changes will result in the new fuel priming pump assemblies providing increased service life.
Adaptable To: The new 162-3904 and 162-3906 Fuel Priming Pump Assemblies are direct replacements for the 2W-2604 and 2W-2606 Fuel Priming Pump Assemblies respectively on these 3500 Commercial Engines.
