Product Overview
The mechanical supply pump draws fuel from the tank and feeds the injection system at the pressure and volume needed for reliable starting and steady engine operation. A worn pump can contribute to hard starting, loss of prime, hesitation under load or repeated fuel-starvation symptoms.
The researched application family cross-references part number 3904374. Case machines can use different engine and fuel-system configurations by serial number, so confirming the old pump number and port orientation is more reliable than ordering by model name alone.
Key Features & Performance
- Mechanical fuel delivery for compatible Case/Cummins diesel applications
- Helps restore prime and consistent supply to the injection system
- Direct identification by 3904374 reference number
- Suitable for repair of weak or leaking original lift pumps
