Part fit perfectly
Part was easy to order and easy to install. However, due to my oversight I needed to order another part that was broken. Once the new part is received, I believe this will fix my problem.

Saved a valuable tool....
If it's leaking air and not firing, this part may save the tool, easy to get into with 4 screws, there were two O rings on it which might be a good idea to replace as well, clean out the head unit a few drops of oil and button it up. Worked perfectly, not sure if they will continue to carry this critical part in the future, hopefully someone ID's the absolute critical parts and keeps making them.
