• Delphi part number FG1644 for catalog and cross-reference lookup

Detailed Description

Delphi FG1644 fuel pump module assembly is engineered for the 2011-2017 Lexus CT200h and supports the vehicle’s fuel delivery and fuel level sensing functions from inside the tank. The assembly includes the pump module, float arm, regulator, and fuel level sender assembly, helping restore proper fuel pressure and tank-level signal output when the original unit is worn or failing. Delphi’s OE background is reflected in the component design, materials, and application coverage for late-model hybrid gas vehicles such as the Lexus CT200h. This part cross-references DFG1644 and SP4145M for the same application.

What It Helps Solve

• Hard starting caused by weak fuel delivery
• Engine hesitation or stalling from low fuel pressure
• Inaccurate fuel gauge readings from a failing sender
• Fuel pump noise or intermittent pump operation
• Driveability issues tied to inconsistent tank fuel supply

Installation Notes and Tips

Compatible with 2011-2017 Lexus CT200h applications. Clean the fuel tank before installing the fuel pump to prevent future seal problems, as noted for this application. Verify electrical connector style, outlet configuration, and pressure requirements before installation. Because this is an in-tank module, access is typically through the fuel tank service opening or tank removal, depending on vehicle service procedure.

Quality Assurance

Delphi builds this fuel pump module assembly using OE experience and application knowledge developed through long-term supplier relationships with major automakers. FG1644 is a standard replacement part intended to meet the fuel delivery and sender requirements of the specified Lexus CT200h fitment.
