Product Overview
A mechanical lift pump for compatible Case loader-backhoes using the Cummins B-series style transfer pump. It feeds diesel from the tank/filter side toward the injection system and includes the hand-priming function on the common pump design.
A worn diaphragm, weak internal valves or leakage at the pump can cause hard starts, fuel starvation under load and repeated need for hand priming. Air leaks and plugged filters can mimic a failed lift pump, so inspect the complete suction side before condemning the pump.
Key Features & Performance
- Restores low-pressure fuel supply to the injection system.
- Mechanical operation avoids reliance on a separate electric feed pump.
- Flange, lever and port arrangement should match the original.
Specifications & Reference Numbers
- Reference number(s): 3970880, 4983584; related Cummins references 3901425, 3903538, 3904374, 3928143, 3966154
- Application family: Cummins B-series mechanical transfer-pump applications
Before You Order
