Product Overview
The primer is used to purge air from the fuel system after filter service, fuel-system repair or loss of prime. A leaking or non-pumping primer can make bleeding the system difficult.
This is not the injection pump; it is the manual priming component used to move fuel and air through the low-pressure side of the system. It is particularly useful after filters, lines or other fuel-system components have been opened.
Key Features & Performance
- Manual plunger pump for purging air from the fuel system
- Useful after fuel-filter changes, line service or a complete loss of prime
- Restores a positive manual priming action when the original pump leaks or will not build pressure

| Output | 41.4 strokes per liter |
