A GM Genuine Fuel Pump Module is a GM-recommended replacement for your vehicle's original component. The jet pump maintains a consistent fuel level inside the internal fuel pump reservoir. These assemblies may be equipped with quiet Generation 4 turbine pumps with integral strainer socks. This original equipment fuel pump module has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
Features:
Designed with guide rods to retain proper alignment while reducing pinching
Include a reservoir and jet pump to prevent fuel pump starvation when the fuel level is low
Most strainers are placed inside the module to help reduce the chance of puncture
Acetyl plastic for good high-alcohol fuel tolerance
Electrical connections are designed to help eliminate high resistance due to vehicle vibration
Benefits of Purchasing a Fuel Pump & Housing Assembly
Purchasing just the fuel pump is less expensive up-front, but a complete Fuel Pump & Housing Assembly provides added benefits:
Extend Service Life: New strainer(s), hoses, sensors and other components help resolve problems that could be caused by more than just the pump.
Reduce Install Time:Since you don't have to disassemble the housing, which could lead to damage, replacement becomes a simple swap, dramatically reducing installation time.
Save Money: The cost of the assembly is often cheaper than buying the components individually, and means you only have to do the job once.
Prevent Premature Fuel Pump Failure
Preventing premature fuel pump failure is far less expensive and time consuming than continuing to replace the pump. There are three common causes for premature fuel pump failure:
ELECTRICAL ISSUES
Poor electrical connections will mimic symptoms of a failed pump, sometimes resulting in unnecessary replacement. Before replacing the pump:
