About this part

Genuine Cummins HPI fuel injector for the QSK60 diesel engine, part number 4326781. The HPI injector is the unit injector of the QSK60's HPI fuel system: the camshaft works each injector through a third push rod on its cylinder, and the engine's electronic fuel controls set the amount and timing of each injection. The injector number depends on the engine's CPL, so quote the number on your injector and your ESN. An engine takes 16.

4326781 supersedes 4088428 and 4087894: Cummins replaced the older numbers with this one, so this is the part to ask for when your parts book or your old part carries one of them. Other numbers for this part: 4326781PX (remanufactured number).

Condition: new surplus, meaning a genuine part bought for a project or a fleet that has not been run in operational service. 16 units available at £1,500 each plus VAT. Please confirm the part number against your engine serial number before ordering. In UK stock — call +44 7951 632187 or message on WhatsApp for shipping and availability.
