Like the title says I'm want to bring this topic back up as it has had good links to metric fuel line. We all buy 1/4" fuel line from the auto parts stores. But the bigger motors want 5/16" fuel line which leaks if you don't put a hose clamp on it. The sweet spot is the 7mm fuel line Honda put on the stock bike but is unavailable at the auto parts store. Sometimes it has a grey coating like stock with a red or black line going down the length. It is pretty spendy but thats what I need. Thanks in advanced for any info on this fuel line.
