About the Aston-Martin Dbs-Superleggera Fuel Pump

The fuel pump delivers pressurized fuel from the gas tank to the engine's fuel injection system. Most modern vehicles use an electric submersible pump located inside the fuel tank, though some older or performance vehicles use an inline or mechanical pump. A failing fuel pump causes poor engine performance, hard starting, stalling, and can leave you stranded when it fails completely.

Replacement Guide

Fuel pump replacement involves accessing the fuel tank, which varies by vehicle. Some vehicles have an access panel under the rear seat or in the trunk that allows direct access to the pump module without dropping the tank. Others require the fuel tank to be lowered from the vehicle, which requires draining or siphoning fuel, supporting the tank with a transmission jack, and disconnecting fuel lines and electrical connectors. Always relieve fuel system pressure before disconnecting any fuel lines. Replace the fuel strainer (sock filter) with the pump. Use new O-rings and seals. After installation, cycle the ignition key several times to prime the system before starting.
