Detailed Description

Delphi FG1852 is a fuel pump module assembly engineered for in-tank installation on select Land Rover Discovery models from 1999 through 2004. It is configured for gasoline use and includes the pump, regulator, fuel level sender assembly, strainer, and vapor pressure sensor in a single service unit. The module uses a pin-style, 4-terminal male connection and a female quick-connect outlet for straightforward fuel line integration. Delphi’s OE background informs the design and component selection, helping maintain the fuel delivery and tank-level functions expected in the original system. This part cross-references Bosch 69340 for the same application.

Common Problems It Can Address

• Hard starting caused by weak or inconsistent fuel delivery
• Engine stalling from low fuel pressure
• Inaccurate fuel gauge readings from a worn sender
• Fuel pump noise or intermittent pump operation
• Driveability issues related to a failing in-tank module

Installation Notes and Tips

Fits 1999 Land Rover Discovery and 2000-2004 Land Rover Discovery, in-tank. For 2000-2004 Land Rover Discovery applications, use without air injection system. Delphi recommends cleaning the fuel tank before installing a replacement pump to reduce the risk of contamination-related failure; fuel tank cleaning kit FC01 is recommended. The package includes the fuel pump module assembly with float arm and instruction sheet. Gasket or seal and lock ring are not included.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplies components to major automakers. The FG1852 is a standard replacement fuel pump module assembly built to reflect that OE-focused background for service use.
