Detailed Description

Delphi FG2086 is engineered as an in-tank fuel pump module assembly for Audi S4 models that require a direct fuel delivery replacement. It includes the pump module, float arm, and instruction sheet, along with an integrated fuel level sender assembly and internal strainer to support fuel pickup and level reporting. The unit is designed for gas fuel systems operating at 12 volts and 51 psi system pressure.

Delphi draws on OE heritage and supplier experience across a wide range of vehicle platforms, and that background is reflected in the FG2086’s application-specific design. This part cross-references 8E0 919 051 AQ and 8E0 919 051 BQ for the same application. For Audi S4 fuel pump replacement, Delphi FG2086 provides a focused service solution for the listed model years.

What It Helps Fix

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent pump output
• Fuel gauge readings that do not match tank level
• Loss of fuel pressure under load
• Driveability issues related to a failing in-tank pump module

Installation Notes and Tips

Before installing a replacement fuel pump module, clean the fuel tank thoroughly to reduce the risk of seal problems and premature pump failure. For the 2007 Audi S4 application, fuel tank contamination is specifically noted as a leading cause of early failure, and use of fuel tank cleaning kit FC01 is recommended. Verify connector style, outlet configuration, and chassis applicability before installation.

Quality Assurance

Delphi builds this fuel pump module using OE-focused engineering and aftermarket coverage developed from long-term supplier experience with major automakers. The FG2086 is a standard replacement part intended to meet the requirements of the listed Audi S4 applications.
