It takes some looking but if you have the inlet and outlet sizes and the approximate length, I usually go to the Gates catalog which has all hoses illustrated.
It's a black and white image so once I find one close in the Gates catalog I'll take the part number then do a Google search of that part number. The search will get you actual images of that hose which will get you a better idea if it will fit for you.
