Detailed Description

Delphi FG1637 fuel pump module assembly is engineered for select 2005-2009 Land Rover LR3 and 2006-2009 Land Rover Range Rover Sport applications with 2 vents. This fuel pump module assembly is built for in-tank installation and includes the pump, float arm, regulator, strainer, and fuel level sender assembly to support fuel delivery and tank level monitoring in one service part. The outlet outside diameter measures 0.375 inch, and the module uses female quick-connect outlets for service-friendly connection points. Delphi FG1637 is a practical choice when replacing a worn fuel pump module on a Land Rover LR3 or Range Rover Sport, especially when the original unit shows signs of pressure loss or sender issues. This part cross-references DFG1637 and E8858M for the same application.

What It Is Used For

• Restoring fuel pressure on a Land Rover LR3 or Range Rover Sport with a failing in-tank pump
• Correcting hard-start or no-start conditions caused by weak fuel delivery
• Addressing inaccurate fuel gauge readings from a worn sender assembly
• Replacing a noisy or inconsistent electric fuel pump module
• Supporting stable fuel system operation at the specified 51 psi system pressure

Installation Notes and Tips

Compatible with 2005-2009 Land Rover LR3 and 2006-2009 Land Rover Range Rover Sport, with 2 vent(s). Before installing a replacement pump module, clean the fuel tank to reduce the risk of contamination-related failure; Delphi recommends fuel tank cleaning kit FC01 for this service. The package includes the fuel pump module assembly with float arm and an instruction sheet. Gasket or seal and lock ring are not included, so verify the condition of the existing sealing components before service.

Quality Assurance

Delphi builds this fuel pump module assembly using OE experience and aftermarket application knowledge developed through decades of supplying major automakers. FG1637 is a standard replacement part intended to meet the needs of the listed Land Rover applications with OE-style fitment and fuel system function.
