The product is great and the delivery was fast. The only problem I have is it is not the right part for out tractor. I was going to return it but it says on your policy that there is a 40% restocking fee and with the cost of postage it will cost me more than I paid for it to return it.
I recommend you offer customers, or inform them they may need to replace the copper washers for the line. Chances are good that if you replace that line, replacement of the washers are probably a good bet
