Show original supplier description
The ACDelco EP158 Electric Fuel Pump is engineered to deliver a consistent and dependable flow of fuel to your vehicle's engine, crucial for maintaining optimal performance. This pump is manufactured to meet or exceed Original Equipment (OE) specifications, ensuring it functions seamlessly for General Motors vehicles and is also compatible with a wide array of other makes and models. Designed for specific fitment, the EP158 operates at 12 VDC with an external mounting location. It features an O-ring seat for both inlet and outlet types, a 2-pin terminal quantity, and a negative ground system. This electric fuel pump plays a vital role in the fuel injection system, pumping fuel from the tank to the injectors under the necessary pressure for efficient combustion. Key signs of wear for electric fuel pumps include poor engine performance, fuel smell, and potential fuel leaks. Regular inspection and timely replacement, especially when these symptoms arise or when diagnostic trouble codes related to fuel delivery issues (such as P0171, P0172, and P0191) are present, are recommended for maintaining vehicle health and safety.
