idkkkk the guys at goodyear always did right on this stuff i bought from them for my truck. theyre all pretty laid back in there and the price difference is alot not just a little and when your talkign alot PER FOOT it really makes a difference especially when id go buy 50ft of line. but whatever floats your boat just throwing money away unless you at least try it. btw the people i have spoken to at amazon were ASSHOLES and 3 of them didnt know what the hell i was talking about when I asked about some stainless steel teflon line.
