w/o Fuel Level Sensor - Must Transfer From Old Unit

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.


  • 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.

GM Genuine Advantages

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:

Poor electrical connections will mimic symptoms of a failed pump, sometimes resulting in unnecessary replacement. Before replacing the pump:
  • Use a Fuel System Tester to test pump pressure is within expected range
  • Use an Electrical Tester to test for bad wiring, burnt or corroded connectors
  • Check / Replace faulty Fuse(s) and Relay


Dirt, rust or debris in the fuel can clog strainers and stick to internal pump components. When replacing the pump:
  • Replace Fuel Filter or Fuel Strainer
  • Empty and clean the tank with Fuel Tank Cleaner
  • Fill tank with fresh, uncontaminated fuel of appropriate grade


Running low on gas causes your fuel to heat up quicker, and your pump to work harder. After replacing the pump:
  • Maintain at least 1/4 tank of fuel and use a Fuel Additive / Conditioner to keep pump cool and lubricated
  • If vehicle is stored without use, drain tank to prevent pump corrosion from fuel oxidation
