Detailed Description

Delphi FG2656 is engineered as a complete fuel module replacement for gasoline vehicles that need dependable fuel delivery and accurate fuel level reporting. The assembly is built for in-tank installation and includes the fuel pump module, fuel level sensor, tank seal, and instruction sheet, helping streamline service on the Chevrolet Express 3500 and GMC Savana 3500. With a 12-volt electric pump, quick-connect outlet, and 4-blade terminal layout, this module is specified for direct-fit service where OE-style dimensions and electrical connections matter.

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers, and that background is reflected in the FG2656’s standard replacement design and broad aftermarket coverage. The module’s 43 psi system pressure, 72.0 psi maximum pressure, and 31 average flow rating support consistent fuel delivery for the listed applications.

What It Helps Solve

• Hard starting caused by weak or failing in-tank fuel pump performance
• Fuel starvation from reduced pump output or pressure loss
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel delivery issues related to a damaged pump module or clogged internal strainer
• Service problems tied to leaking tank seals at the module interface

Installation Notes and Tips

Before installing Delphi FG2656, clean the fuel tank to reduce the risk of contaminating the replacement pump. Delphi notes that fuel tank contamination is a leading cause of premature fuel pump failure, and use of fuel tank cleaning kit FC01 is recommended for the listed Chevrolet Express 3500 and GMC Savana 3500 applications. Confirm the vehicle’s emission configuration, chassis type, and fuel line setup before service.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed through long-term supplier experience with major automakers. FG2656 is a standard replacement fuel pump module assembly designed to meet the needs of the specified gasoline applications.
