OE-Based Fuel Delivery Design

Delphi FG1987 is engineered for select Mercedes-Benz compact models, including the 2015-2020 Mercedes-Benz GLA250 and the 2014-2019 Mercedes-Benz CLA250 without Sport Package. This fuel pump module assembly is designed for in-tank installation and uses an electric pump with a 10-amp average current draw, quick-connect outlet, and integrated fuel level sender for consistent fuel system operation. The part number FG1987 is also a useful reference when cross-checking replacement needs for the same application.

This part cross-references 246 470 09 94 and CFG1987 for the same application.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel pressure
• Fuel starvation under load from a failing in-tank pump
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel delivery interruptions related to a restricted or aging module
• Driveability issues tied to contaminated tank components

Installation Notes and Tips

Before installing FG1987, clean the fuel tank to reduce the risk of premature seal or pump problems caused by contamination. Delphi recommends using fuel tank cleaning kit FC01 for the CLA250 application. Verify the vehicle’s build details, including the CLA250 without Sport Package requirement, and confirm connector, outlet, and sender specifications before installation. The package contents include the fuel pump module assembly with float arm and instruction sheet; gasket or seal and lock ring are not included.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplier knowledge developed with top automakers. That OE heritage is reflected in the FG1987 fuel pump module assembly, which is built as a standard replacement for select Mercedes-Benz GLA250 and CLA250 models.
