Features: The pump is prone to failure if the fuel system has any water or contaminated fuel introduced to it. When the pump fails, it will send metal contaminants throughout the entire fuel system which in most cases will ruin the injectors and other sensors. The system-saver inlet valve was designed to offer you peace of mind in the event of a pump failure. The important difference between the oem valve and the system-saver is the improvement made to the screen, which is upstream-of the valve inlet. This micron-rating and double-wrap construction will do a much better job of keeping debris from entering the rest of the fuel system. It is also constructed in a manor-where it will not be able to tear or de-laminate from the filter housing. It will load up quicker than the factory screen in the event of a pump failure. This will choke off the valve-sooner, which will bring the truck out of service and shut-it down in a shorter amount of-time. This is all positive for improving the chances injectors won't need to be replaced when a pump has failed. The screen and housing are constructed from stainless steel for corrosion resistance. And, as-always, you-can trust that exergy-products have been properly de-burred and are assembled using appropriate processes to ensure proper cleanliness.
