Where to get correct zip ties for fuel lines

[Baja 252]

I've always just used regular zip ties, but I've heard you shouldn't use them for fuel and vacuum lines. I guess the head of it should be curved to fit the hose better?
Where (other than Yamaha) do you get the special ones?

I found them on eBay. I think it was just the McMaster ones. It was like $15 for 100. They included some smaller ones that work great on primer lines.
