Whay replace the hose? Is it leaking? If not no reason to replace it. Theo great recommendation. For most membrnae compressors you will need to get the device to mount them as well. It is easy to hookp to your hose and is self sinking by filling with rocks. Teh entire coactvie airstation is only $150. I agree with Sue if your compressor has not been maintainted it is underperforming as well.
