Anyone on here ever do this and do you have any tips? Is there anything I can put on the hairline cracks to keep them from getting worse? A liquid plastic like you can coat tool handles with comes to mind. A replacement hose is going to be over $200.
Doesn't the hose need to flex? I wouldn't bother with this.
But if the manu. wants too many bucks because he knows you are locked into his product, get any kind of corrugated hose and run the wires.
How high is the higher voltage? It may not be 120v; they could use lower voltage and a high current (how long are the wires and what diameter) motor to get the same hp.
