    I was a little heasitant to order this being it was expensive. But right out of the box i could tell it was the exact pump that I had on my compressor. Quality built have put almost 30hrs on this compressor allready and it builds air just like it did when the old pump was new. Verry happy with it. Do note that the picture on the website does not match the compressor shipped exactly. It is correct however the compressor that you get has the cooler for the discharge air.
