Autobest® Fuel Pump Module Assembly F4857A

Autobest Fuel Pump Module Assembly are featured as follows:

• Made with the best quality materials to ensure great product quality.
• They are tested in many points of the manufacturing process to make sure that it is durable and reliable.
• Allows fuel flow from the tank to the engine.
• The production takes place following strict regulations so as meet or surpass those of an original manufacturer.
• Contains a plastic molded fuel-resistant reservoir for holding fuel under all operational conditions.
• Fuel pump transports fuel at high pressure through vehicle's fuel system.
• The float and sender unit complement each other to measure for measuring amounts of gas inside the tank which is then communicated on the fuel gauge.
• Has a spring that expands due to temperature change, which maintains the reservoir low in the tank and eliminates chances of starvation.

The Autobest Fuel Pump F4857A is a durable, high-quality part of a fuel delivery system that ensures fuel is supplied from the tank to the engine. For this reason, the pump unit has been built in compliance with strict guidelines that aim at meeting and exceeding the requirements of an original equipment manufacturer (OEM). The module includes a plastic molded fuel resistant reservoir, a fuel pump, float and sender unit, spring and strainer. It operates by pumping fuel in pressure to the vehicle’s fuel system through the spring and strainer. On the other hand, float and sender unit gauge measure the level of fuel in the tank after which it sends them to electronic instrument panel so as to be read by drivers on their dashboard gauges. Last but not least, when temperature rises or falls to certain levels, spring will stretch or shrink respectively so as to keep reservoir at the bottom hence preventing petrol starvation. Strainer performs filtration of gasoline before it enters into fuel systems. During production Autobest Fuel Pumps are subjected through all stages for testing purposes so as to ensure they offer unmatched performance as well as last long enough.
