The ACDelco Electric Fuel Pump Assembly and their related components are designed to meet the highest standards in the industry. This helps to ensure their ability to provide impressive fuel delivery performance, quick engine starts and continuous fuel supply, minimum noise and vibration, long-lasting durability and easy installation and fit. The ACDelco Fuel Pump is manufactured in ISO-9001 and QS-9000 registered facilities, quality is assured and backed by competitive warranty coverage.

Product Features:

• Hybrid Modular Reservoir Assembly (MRA)
• Latest fuel level sensor design eliminates failures due to worn fingers on sensor wiper arm, sulfur contamination, wire wound sensors and lead sensor kits
• Improved electrical connections that eliminate below-cover burning due to vehicle vibration over previous designs
• Improved pump design to increase pump life and reduce pump noise over previous designs
• Pump changed from a roller vane design to a ge-rotor design
• The ACDelco fuel pump line includes: electric (in-line and in-tank), modular assemblies and mechanical pumps.

Fuel modules are designed to provide uninterrupted flow of fuel to the engine at system pressure. Depending on customer needs, the Delphi Series 7000 Fuel Module can integrate a pump, fuel level sensor, fuel filter, reservoir with active and passive filling mechanisms, and regulator in a compact, modular package that is easy to install. The Delphi Series 7000 Fuel Module also offers an in-tank fuel filter with 10-12 µm filtration. The Delphi Series 7000 Fuel Module provides superior low fuel handling and fuel level sensing performance with its enhanced bottom reference design. It also offers reduced noise levels and improved pump durability compared to conventional fuel modules. The simplicity of design also results in lower cost. This module is targeted to meet California ZEV requirements.

Product Features:

• Acetal cover can accommodate 116mm tank opening to permit integrated filter in reservoir
• Single stage turbine pump provides quiet, energy efficient operation
• Active reservoir-fill mechanism (high pressure jet pump) to maintain fuel supply in reservoir
• Passive reservoir fill mechanism helps fill the reservoir at low-fuel volumes
• High capacity filter media helps supply clean fuel to the injection system
• Available serviceable in-tank fuel filter for markets with poor quality fuels
