The rest of the hose looked fine, so before I spend $150 on a new hose wondering if anyone had any ideas. I don't know if there's any easier way to replace just the plastic connector rather than the whole assembly or some other clamp I can't think of.

This is the part, you can see how once the outer plastic ring cracks there's only one tooth holding it in. Annoyed I discovered this 2 days after FCP Euro ended their 10% off sale.

If you leave stuff in your basket after a day or two they will email you a 5% off code. Not a common failure as far as I know, so probably won't need a free replacement from FCP, just get it where you get the best price.
