Detailed Description

Delphi FG1234 is engineered for Mercedes-Benz C230, C240, and C320 models listed below, with fitment tied to specific chassis breakpoints. Delphi draws on OE heritage and decades of supplier experience to build aftermarket fuel system parts with the specifications needed for proper fuel delivery, sender operation, and in-tank installation. This part cross-references Bosch 67970 for the same application.

Delphi FG1234 is a direct-fit fuel pump module assembly for select Mercedes-Benz C-Class vehicles where the original in-tank module has worn out or lost pressure.

What It Helps Fix

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent pump output
• Fuel gauge errors related to sender wear
• Low fuel pressure conditions in gasoline systems
• Noise or failure from an aging in-tank pump module

Installation Notes

Confirm chassis breakpoints before ordering, since fitment is limited to the listed Mercedes-Benz C230, C240, and C320 applications. Clean the fuel tank before installation to reduce the risk of contaminating the replacement pump; Delphi and the fitment notes recommend using fuel tank cleaning kit FC01. The package includes the fuel pump module assembly with float arm, seal, and instruction sheet. Lock ring is not included.

Quality Assurance

Delphi builds this fuel pump module using OE-based engineering knowledge developed through long-term supplier experience with major automakers. The FG1234 is a standard replacement part designed to meet the needs of select Mercedes-Benz fuel system service work.
