- Blade-type male terminals with six connections for secure electrical fitment
- Standard replacement grade with regulator included for optimal fuel pressure control
Technical Specifications and Features
The Delphi FG1577 fuel pump module assembly operates at 12 volts and is designed specifically for gasoline fuel systems. It features a 0.313-inch outlet outside diameter with a quick connect outlet type, facilitating straightforward installation. The pump includes an internal strainer and a fuel level sender assembly with a float arm, eliminating the need for an external strainer. The module has six blade-type male terminals, ensuring compatibility with the vehicle’s wiring harness. Resistance values range from 50 ohms when empty to 990 ohms when full, supporting accurate fuel level readings. This in-tank electric pump module is positioned on the right side of the fuel tank and comes with a regulator to maintain consistent fuel pressure.
Compatible Vehicles and Applications
This fuel pump module assembly is compatible with a range of Mercedes-Benz vehicles, including the C300, C350, CLS400, CLS550, E350, E400, E550, and GLK350 models. It is designed to replace the original equipment fuel pump module in these vehicles, ensuring proper fuel delivery and fuel level monitoring.
- Resolves fuel delivery issues such as engine stalling or hesitation
- Addresses inaccurate fuel gauge readings due to faulty sender assembly
- Replaces worn or damaged fuel pump modules to restore fuel system performance
- Helps eliminate fuel pressure fluctuations affecting engine performance
Installation Notes and Tips
Installation of the Delphi FG1577 fuel pump module assembly requires removal of the fuel tank or access through the service panel, depending on the vehicle model. Ensure the electrical connectors match the six blade-type male terminals and verify the quick connect outlet fits securely. It is recommended to inspect the fuel tank for debris before installation and replace any seals or gaskets as needed, since this module does not include a gasket or lock ring. Follow all safety precautions when working with fuel system components.
Quality Assurance and Warranty
The Delphi FG1577 is a standard replacement grade fuel pump module assembly manufactured to meet OEM specifications. It includes a regulator and fuel level sender assembly to maintain system integrity. Delphi products undergo rigorous testing to ensure durability and performance. Warranty coverage details should be confirmed at the time of purchase, as they may vary by distributor.
