I just called autokrafter,  to order a flex hose for my intake. They had them listed in their catalog for $19.99. After I haven't the lady the part number, she told me that they were $49.99, which is way more than what I was looking at. She said that the part had been discontinued, and would no longer be made by their vendor.  I didn't buy it. So if anyone needs one, they have one left. I won't pay that, just for the sheer fact that they bumped it up, over double, because it was the last one. I did find one on ebay for $31.95, which is more than I wanted to spend, but bought it anyway.
