Detailed Description

Delphi FG1509 is engineered as an OE-style fuel pump module assembly backed by Delphi’s long history supplying original equipment to major automakers. This in-tank electric unit is specified for gas fuel systems and supports a maximum pressure of 109 psi with a 58 psi system pressure rating. It also features a 13.0-volt design, an average current draw of 10 amps, and an average flow rating of 20, making it a practical replacement for fuel delivery service on the Chevrolet Impala.

For fitment-specific searches, this part fits 2008 Chevrolet Impala, N/A, and fits 2009-2010 Chevrolet Impala, N/A. It is listed for Partial Zero Emissions Vehicle applications, with notes excluding the fuel tank sending unit on the covered vehicles. Delphi FG1509 also includes the fuel level sender assembly, which helps restore accurate fuel level reporting when the original module is worn or failing.

Common Problems This Part Can Address

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent pump output
• Fuel gauge errors related to a failing sender assembly
• Low fuel pressure conditions in the tank-mounted system
• Noise or wear from an aging in-tank pump module

Installation Notes and Tips

Before installing a replacement fuel pump module on a Chevrolet Impala, clean the fuel tank to reduce the risk of debris contaminating the new pump. Delphi recommends using fuel tank cleaning kit FC01 for this service. Confirm the vehicle’s fuel system configuration against the listed fitment notes, especially the Siemens Fuel Systems Only note for 2008 applications and the Partial Zero Emissions Vehicle coverage.
