Features: The pump is prone to failure if the fuel system has water or contaminated fuel. When the pump fails, it sends metal contaminants throughout the entire fuel system, destroying the injectors and other sensors in most cases. The system saver valve is designed to give you peace of mind in the event of a pump failure. The important difference between the OEM valve and the system saver valve is the improvement of the strainer, which is located upstream of the valve's inlet. This micron rating and dual winding design will do a much better job of preventing debris from entering the rest of the fuel system. It is also constructed in a way that prevents it from tearing or delaminating from the filter housing. It will load faster than the factory strainer in the event of a pump failure. This will throttle the valve sooner, which will take the truck out of service and shut it down in a shorter amount of time. This is all positive for improving the chances that the injectors will not need to be replaced when a pump has failed. The strainer and housing are made of stainless steel for corrosion resistance. And as always, you can trust that exergy products have been properly deburred and assembled with appropriate processes to ensure proper cleanliness.
