Measure how much you need, measure the inside diameter of current hose, then go to your local auto parts store and pickup the same amount of hose. The hose should be no larger then 5/8 ID. Don't buy the thin wall cheap stuff, need a good thick wall hose so it does not kink in the bends
I like Gates hose and can find online easy enough. Search [FONT="]Gates Green Stripe[/FONT]
