A common fault with this model compressor are air leaks in the end cap of the dryer.
The source material is plastic and eventually appear air leaks.
Air leaks in the dryer can cause a reduction in pressure, well as extending the time taken to lift the vehicle, etc.
The original design is poor and cracks can develop around the connectors on the air line causing leaks and failures of the vehicle.
This new end cap dryer cover is made of duralumin and solves this problem.
