Detailed Description

Autobest F4774A is a fuel pump module assembly for the Audi A4 that combines the pump and level-sending components into one in-tank unit. The assembly uses a turbine-style pump, POM housing, FKM seal material, and an internal strainer to support consistent fuel delivery in 12V systems. With a 14-amp average current draw and a 305 ohm empty / 55 ohm full resistance range, it is specified for replacement work where accurate fuel level reporting and steady pressure are required. This part number, F4774A, is intended for 2005-2009 Audi A4 vehicles and is supplied as a fuel pump and kit package.

Common Replacement Reasons

• Hard starting caused by weak fuel pressure
• Fuel starvation under load or at higher demand
• Inaccurate fuel gauge readings from a failing sending unit
• Intermittent pump noise or loss of fuel delivery
• Stalling related to an aging in-tank fuel module

Installation Notes and Tips

Verify connector style, outlet size, and tank configuration before installation. This in-tank module uses a male racetrack connector, 3/8 in. quick-connect outlet, and 4-pin terminal layout. Replace the tank seal or gasket if required by the vehicle service procedure, since a gasket or seal is not included. Confirm the fuel strainer is seated correctly and inspect the tank for contamination before installing the new module.

Quality Assurance

Autobest states that each fuel pump is built from top-grade components and tested throughout manufacturing to help maintain product consistency. The F4774A is backed by a limited lifetime warranty and is supplied with materials selected for ethanol tolerance in today’s fuel systems.
