Was wondering if there was a way to test a set of old cummins non top stop injectors with out special tools or testing equipment...I've read through the TM's and obviously don't have access to the equipment they specify to use...The reason why I ask is that I recently had a brand new injector hang closed and I still have the full set of the old injectors I removed...Any tips or tricks for cleaning,inspecting and "back yard" testing the old ones to see if they would be fit to use again would be a great help...Thanks again.
