Mercedes-Benz Fuel Pump Module Assembly

Delphi FG1577 is a right-side in-tank fuel pump module assembly for select Mercedes-Benz models. It combines the electric pump, fuel level sender assembly, and regulator in one OE-style replacement built for 12-volt gasoline applications.

Key Features

  • In-tank electric fuel pump module assembly for gasoline systems
  • Includes fuel level sender assembly and regulator
  • Quick-connect outlet with blade terminals and 6-terminal configuration
  • Standard replacement design for select Mercedes-Benz right-side applications
  • Delphi OE heritage backed by 100 years of original equipment experience
  • Part number FG1577 for ordering and cross-reference use

Detailed Description

Delphi FG1577 is engineered for Mercedes-Benz fuel delivery systems that use a right-side in-tank module. It is built for 12.0-volt operation, gasoline fuel, and electric pump performance with an internal strainer design, quick-connect outlet, and integrated fuel level sender assembly. The module also includes a regulator, helping restore proper fuel delivery and tank level reporting in one service part. Delphi applies OE knowledge gained from supplying top automakers, and that experience is reflected in the fit, function, and component layout of this fuel pump module assembly. This part cross-references Monroe Shocks & Struts (e.g., CFG1577, E9111M) for the same application. FG1577 is a direct replacement choice for Mercedes-Benz CLS550, E400, E550, CLS400, E350, C350, GLK350, and C300 right-side fuel pump service.

What It Helps Fix

  • Hard starting caused by weak or failing fuel delivery
  • Engine stalling from inconsistent fuel pressure
  • Fuel gauge errors related to sender assembly wear
  • Poor acceleration from restricted or unstable fuel supply
  • Fuel pump noise or intermittent pump operation
