Detailed Description

Autobest F4935A is engineered as a replacement fuel pump module assembly for Mercedes-Benz GL450, GL550, ML350, ML500, and ML550 models listed in the fitment data. It is an in-tank unit with a quick-connect 5/16 outlet, male connector, and integrated fuel sending unit for fuel level feedback. The module uses a POM housing, NBR seal material, and a turbine-style pump to support stable fuel delivery under demanding operating conditions.

This part cross-references Delphi FG1163 for the same application. If you are replacing a worn Mercedes-Benz fuel pump module assembly, this part number, F4935A, is a direct-fit option for the specified right-side and module applications shown below.

What It Helps Fix

• Hard starting caused by weak fuel pressure
• Engine stalling from inconsistent fuel delivery
• Fuel gauge readings that no longer match tank level
• Loss of power under load from a failing in-tank pump
• Fuel system noise associated with pump wear

Installation Notes and Tips

Verify the vehicle’s year, model, and position before installation. Fitment includes right-side passenger-side pump applications on several Mercedes-Benz ML and GL models, along with module applications for select GL and ML vehicles. Confirm connector style, outlet type, and fuel tank configuration before removing the original assembly. Because this is an in-tank fuel pump module assembly, clean the tank area and inspect the sealing surface before reassembly.
