damn im going with them 6n 15' for 55 bucks with fittings and crimpedcab said:www.cp-performance.net (cp-performance on ebay) sells Parker steel braid line. Get the -6 size, as it's equivalant to 3/8" ID. The ends are swivel flared ends and you can find fittings for it at most local places, including the Parker store, which is where I recommend. I run a Campbell Hausfield (however you spell it) water seperator from Lowes and it works just fine. It's got 3/8 females on each side. I ran a 15 foot steel braid line from the compressor to my tank, and I've got a little slack. 15 ft should be just fine.
