This is the Delphi BEBJ1B00001, a new fuel injector, not a rebuild, for the Paccar MX-13 12.9L engine built to the EPA10 standard. It crosses to Paccar 1825900, also sold as 1825900PE and 1825900PEX. The engine takes six.
Later MX-13 engines are listed with different Delphi injectors, so match the injector by the number on the old one and by engine serial number. A miss, low power, hard starting or a cylinder cutout fault can point at an injector, but check fuel supply and filters first.
Confirm Fitment Before You Order
This injector is listed for the EPA10 MX-13. Later MX-13 engines are listed with different injectors, such as Delphi EX631158 for the model year 2015 engine. Send us the engine serial number or VIN and the number on your old injector. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
