nightwalkerancestery Posted March 9, 2015 Report Share Posted March 9, 2015 It's a 5/16 line. 3/8 (6an) hose will do. There's some info I posted on hose diameters for AN fitting conversion in the FAQ section. Should be everything you'll need. - Charles Link to comment Share on other sites More sharing options...
