Fuel System Saver Inlet Metering Valve

The Exergy Fuel System Saver is an upgraded Inlet Metering Valve (also known as FCA or MPROP) designed to protect your high-dollar fuel system components from potential CP4.2 pump failures. The primary concern with CP4 pump failure is the spread of metal contaminants throughout the fuel system, which can ruin injectors and other sensors, leading to costly repairs. This upgraded valve directly addresses this issue. At the core of the Exergy System Saver is an improved inlet screen. The factory screen is a single-layer, 80-micron mesh that is prone to tearing. In contrast, the Exergy screen is a dual-layer, 25-micron mesh mounted on a stainless steel frame. This finer filtration is over eight times more effective than the stock screen and its layered construction provides enhanced protection against debris. According to Exergy, injector survivability in systems with a failed CP4.2 pump and a System Saver installed is increased by over 85% compared to systems with the factory screen. The stainless steel construction also ensures corrosion resistance and durability. Installation is straightforward as this unit is a direct factory replacement, requiring no modifications. The Exergy System Saver is designed to prevent the metal shavings from a CP4 pump failure from spreading to the rest of your fuel system. If a pump failure does occur, Exergy recommends replacing the pump and only replacing injectors if symptoms persist after the pump replacement. The upgraded screen can also help mitigate issues related to traditional metering valve failures, such as idle surge and excessive rail pressure fluctuations. This part serves as a direct replacement for Bosch part numbers 0 928 400 779 and 0 928 400 757, as well as GM part number 12641035 and ACDelco Part number 12641035. It comes with mounting bolts and is backed by a 2 Year Unlimited Mile Warranty.
