I bought a 95 ECLB last week because the previous owner couldn't get it running. It had been at a shop that works on Cummins with little knowledge of Powerstrokes. I have chased it down to the IPR. It has a newer IPR valve on it with no edge filter. The original one is laying in the floor and has the edge filter. Which one do I need or does it matter?
