I am very a knowledgeable about the Ingersoll Rand pump repair kits. I know what I can see in front of me and I can compare it to pictures but it really doesn't mean anything at the end of the day. What you see in the pictures is exactly what is in this box. I don't feel as if it's complete. You have to study the pictures and you have to bid your judgment you are going to receive exactly what is in these pictures
