Autobest F4857A Fuel Pump Module Assembly

Fuel Pump Module Overview

The Autobest F4857A fuel pump module assembly is built for direct in-tank fuel delivery service with integrated sending unit support. It is a fitment-based replacement for the Volvo XC90 and uses a turbine-style pump, male connector, and internal strainer for a complete module-style repair.

Key Features

• In-tank fuel pump module assembly with a turbine pump design.
• Includes the fuel sending unit and strainer for module-level replacement.
• 12V electrical design with a single male rectangular connector.
• FKM seal material and POM housing for fuel system durability.
• Average flow rating of 54.2 GPH and average current draw of 9.5 A.
• Limited Lifetime Warranty.

Detailed Description

Autobest Fuel Pump Module Assembly F4857A is engineered as an in-tank replacement for the Volvo XC90, covering 2005-2014 applications. The module combines the pump and sending unit in one assembly, which helps restore fuel delivery and fuel level signal function when the original unit is worn or inconsistent. The internal strainer, 7-pin male terminal layout, and negative-ground 12V electrical setup support a straightforward OE-style replacement approach. This part cross-references Delphi FG1275 for the same application.

The Autobest Fuel Systems program focuses on fit, form, and function with application coverage built around problem-solving replacement parts. For Volvo XC90 fuel pump module replacement, F4857A provides the core components needed for a module-level repair rather than a pump-only service part.

What It Is Used For

• Restoring fuel pressure when the original pump can no longer maintain delivery.
• Correcting inaccurate fuel level readings caused by a worn sending unit.
• Replacing a noisy, weak, or intermittent in-tank fuel pump module.
• Addressing drivability issues tied to fuel starvation under load.
• Repairing a leaking or degraded module seal at the tank interface.

Installation Notes and Tips

Fits 2005-2014 Volvo XC90, N/A. Verify connector style, terminal count, and tank configuration before installation. This module is designed for in-tank use and does not include mounting hardware. Confirm the fuel system is depressurized and the tank area is clean before removing the original assembly.

Quality Assurance

Autobest backs this fuel pump module assembly with a Limited Lifetime Warranty. The design uses a turbine pump, FKM sealing material, and a module-style construction intended to support consistent fuel delivery and sender operation.
