Product Overview
This hand primer is used to pull fuel through the system and remove trapped air after filter changes or fuel-system service. A primer that will not become firm may also point to an air leak elsewhere in the system.
Before replacing the pump, check the fuel filter, tank pickup and hoses for restrictions or air leaks. Those problems can make a good pump look weak and cause the same hard-start or power-loss symptoms.
Key Features & Performance
- Supplies or primes fuel for the engine
- Helps restore normal fuel delivery when the original pump is weak
OE / Reference Numbers
- No additional reference number was added without stronger verification.
