Product Overview
This pump supplies low-pressure fuel from the tank side of the system to the engine. A weak pump can cause long cranking, loss of power under load or trouble keeping the fuel system primed.
Before replacing the pump, check the fuel filter, hoses and tank pickup for restrictions or air leaks. Those problems can make a good pump look weak and can cause the same hard-start or power-loss symptoms.
Key Features & Performance
- Supplies fuel to the engine or injection system
- Helps restore normal fuel delivery when the original pump is weak
OE / Reference Numbers
- No additional reference number was added without stronger verification.
