Autobest F4149A Fuel Pump Hanger Assembly Module

The Autobest F4149A is a complete fuel pump hanger assembly module designed to replace worn or failed original equipment. This integrated assembly combines all essential fuel delivery and monitoring components in a single, drop-in replacement unit, ensuring reliable fuel system operation.

Complete Module Assembly Includes:

• Fuel Reservoir: Molded fuel-resistant plastic body that maintains a reserve fuel supply during all operating conditions, functioning as a tank within the tank to prevent fuel starvation
• Fuel Strainer: External filtration system that removes contaminants before fuel enters the module assembly, ensuring clean fuel delivery to the engine (some applications include both external and internal strainers)
• Electric Fuel Pump: High-pressure electric pump that delivers fuel from the tank to the engine under proper pressure
• Fuel Level Float: Precision float mechanism attached to the sender unit for accurate fuel level measurement
• Fuel Sender Unit: Electronic sending unit that works with the float assembly to transmit accurate fuel level readings to the vehicle's dashboard gauge
• Stabilizing Spring: Temperature-compensating spring that expands and contracts based on operating conditions to keep the reservoir properly positioned at the bottom of the fuel tank

This hanger assembly is engineered to meet OE specifications for fit, form, and function, providing a reliable solution for restoring proper fuel pump and fuel level sender operation in your vehicle's fuel system.
