The likely cause of the faults noted above will be a leak on the compressor, worn piston seals or saturated filters. This results in reduction of compressor output and triggers vehicle faults as well as extending the time taken to lift the vehicle. This auction is for our replacement dryer filter kit and improved design replacement dryer end cap that eliminates the common leak on the dryer end cap. The original design is poor and cracks can develop around the air line collets causing leaks and vehicle faults. Please check out our store to see our complete repair kit for all common failure parts on this compressor or for filter repairs or piston seal repairs independently
