Includes Sender and Level Sensor
GM Genuine Fuel Pump and Level Sensor Modules are designed to provide excellent fuel delivery performance, quick engine starts, continuous fuel supply, long-lasting durability, and correct fit for simple installation. These modules include quiet and durable Generation 4 Turbine pumps and are engineered with Acetyl plastic for good high alcohol fuel tolerance. They are qualified to meet the original model year specific requirements for both Environmental Protection Agency (EPA) and California Air Resources Board of Emissions (CARB) certifications. GM Genuine GM OE Fuel Pump and Level Sensor Modules are available in many variations and include a durable GM Genuine GM OE Fuel Level Sensor in addition to the GM Genuine GM OE Electric Fuel Pump and its associated components.
Features
Designed with guide rods to retain proper alignment while reducing pinching
Includes a reservoir and jet pump to prevent fuel pump starvation when the fuel level is low
Strainer is placed inside the module to help reduce the chance of puncture
Float material has good fuel resistance properties for longer life
Electrical connections are designed to help eliminate below-cover burning due to vehicle vibration
Designed for increased pump life and reduced pump noise with regard to previous models
Level sensor designed with thick wiper contacts and wear pads that provide durability, especially with today's ethanol fuels
Level sensor design helps eliminate complications due to worn fingers on the sensor wiper arm, sulfur contamination, and failures of wire wound sensors and/or lead sensor kits
GM Genuine Advantages
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:
