Detailed Description

Delphi FG1550 is a fuel pump module assembly engineered for in-tank installation on select BMW 528i, 535i, 535i GT, and 640i applications, including xDrive and Gran Coupe variants listed in the fitment data. The module includes a regulator and external strainer, and it uses a quick-connect outlet with a pin-style terminal layout for service replacement. Delphi draws on more than a century of OE supply experience, and that background is reflected in the design approach used across its aftermarket fuel delivery parts. This part cross-references BMW 16 11 7 341 301 and Delphi CFG1550 for the same application.

What This Part Helps Address

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel starvation under load or during acceleration
• Low fuel pressure from a worn in-tank pump module
• Driveability issues tied to unstable pump output
• Fuel system service needs on BMW 528i, 535i, 535i GT, and 640i models
