i also use ordinary black rubber fuel injection hose.

but on the machines i ride the most i change the way the carbs run all the time so the fuel lines seldom get used for more than a year.

having said that, it works well, and when i change the lines i toss the used lengths back into a milk crate to use again if they're still in good shape.

every day you do not take a chance is a day of your life that you will never get back.
