I had a friend replace the air suspension compressor pump with a used one that I bought on ebay. The air compressor pump is located under the windshied washer fluid container. You have to take a cover plate off to get to it or even see it. We discovered that the top of the air suspension compressor pump, where the air hose goes into it, screws off with a crescent wrench. So we just left the hose attached to the top of the pump and replaced the body of the the pump. I have no idea how you would just replace the hose.
