Product Overview
Use the primer to purge air after fuel-filter service or other work that opens the fuel system. Replacement is appropriate when the plunger leaks, sticks or will not build fuel pressure.
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
