Cummins 3976371 Fuel Injector Sealing Washer

This Cummins 3976371 Copper Injector Sealing Washer is a Brand New OEM Cummins part.

What can happen if I reuse my original fuel injector sealing washers?

If you decide not to replace these sealing washers, the high compression produced by your diesel engine will escape around the fuel injector. All of your power will escape around the outside edge of your fuel injector. The loss of engine compression will produce a complete mess of the fuel injectors and fuel rail.
