Two hard fitment gates apply:
EPA13 only. Paccar uses different MX-13 injector calibrations for EPA10, EPA13 and EPA17 engines. Confirm your engine’s emissions year and read the Paccar number on the injector you are removing.
MX-13, not MX-11. The MX-11 uses a different injector.
Installation: inspect the injector sleeve (Paccar 2401056) and replace the injector O-ring (Paccar 1629458) at every installation. Clean the injector bore before seating the injector.
Quantity: six per engine.
Other versions available: Delphi remanufactured EX631145.
Common interchanges: 1972591, 1925657, 1952045, 2005596, EX631145
Conclusion:
This remanufactured Delphi F2P injector replaces Paccar 1925657 and 1972591 on 2013-2017 MX-13 EPA13 engines. Confirm your emissions year — other MX-13 tiers use different injectors.
