Well, I'm going to go against the grain here. IMO, if it was sold with hose that said it was not for this use, then it should be fixed at no cost to the buyer. The way I'm reading this is the seller will repair it at cost. Why should the buyer pay for the sellers mistake? I agree that race motors don't carry warranties. But this is not a warranty issue, IMO. The seller went against the product specifications and it broke. IMO, it is his fault, not the buyers...
