Product Description ACDelco Gold (Professional) Electric Fuel Pumps are a high quality alternative to Original Equipment (OE) parts. Electric fuel pumps are used on engines with fuel injections to pump fuel from the gas tank to the injectors. The pump must deliver the fuel under high pressure so that injectors can spray fuel into the engine. Fuel pressure must be within specifications for the engine to run correctly. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. &#9888;<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov
