Product Overview
The assembly provides low-pressure fuel supply and manual priming capability. It is especially useful after filter changes or fuel-system service, when trapped air must be purged before the injection pump can build pressure normally.
Zexel produced many pump variants with similar external appearance, so the two reference numbers and the original pump's thread/mounting details should be treated as the primary fitment check rather than guessing from engine brand alone.
Key Features & Performance
- Combined feed/primer function for compatible Zexel diesel systems
- Cross-references 105210-1800 and 105210-4280
- Useful for restoring manual priming after filter service
- Part-number matching is essential because similar Zexel pumps use different fittings and mounting details
