This part cross-references Spectra Premium SP6677M for the same application. Delphi FG1743 is also referenced by part number DFG1743 in interchange listings.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent fuel pressure
• Fuel gauge errors related to a failing sender assembly
• Fuel pressure loss from worn internal pump components
• Driveability issues tied to contaminated or aging in-tank pump modules

Installation Notes and Tips

Before installing Delphi FG1743, clean the fuel tank to reduce contamination-related seal and pump problems. Delphi notes that fuel tank contamination is a leading cause of premature fuel pump failure, and a clean tank helps protect the replacement module. Verify the vehicle’s fuel system configuration and confirm fitment for the exact year, make, and model before installation.
