Product Overview
After a filter change, fuel-line repair or a machine sitting empty, trapped air can make a diesel difficult or impossible to start. A primer that leaks, will not draw fuel or no longer builds resistance can also make normal bleeding procedures frustrating.
This replacement hand/priming pump restores the manual fuel-priming function so air can be purged and fuel can be drawn through the low-pressure side of the system before starting.

Model names alone are not always enough to confirm fitment when manufacturers made serial-number or engine changes.
