The rubber hose with the metal wire are hard to get a hold of at at local stores and I couldn't find it on mcmaster. I ended up just buying from thrust innovations. think it was like $25 for the two pieces. I wouldn't go for something else because you'll end up with water leaking into your hull...
I think at one point I did eventually find the manufacturer, its an industrial hose and you can't just buy like 2 or even 10 feet from them... its a big roll.
