Product Overview
The lift pump draws fuel from the tank and supplies the injection pump at low pressure. When output falls off, the engine may be difficult to prime, start normally but lose power under load, or stall as the injection pump outruns the available fuel supply.

Before You Order
Confirm the pump's inlet/outlet orientation, mounting flange and reference number because Case/Cummins applications use more than one lift-pump configuration. Diagnose filters, tank venting and suction hoses at the same time.
Frequently Asked Questions
What does the lift pump feed?
It supplies low-pressure fuel from the tank/filter side to the diesel injection pump.
Can a clogged filter mimic a bad pump?
Yes. A restricted filter or suction line can create the same power-loss and hard-start symptoms.
Why are several part numbers listed?
This pump family has been sold under multiple Case/Cummins supersession and cross-reference numbers.
