It's kinda pointless to buy a "kit". You usually pay more just to have it precut for you. I just went out to the car and measured all the hoses I wanted to replace, and ordered an extra couple feet. I believe there was three different sizes.
I'm not a big fan of Weapon-R products, but their silicone hose is AWESOME. It looks badass and has held up for over 3 years with no signs of wear. You can see some of it here...I used excess to cover random things in the bay.
It actually has metallic color shift to it like paint. 8D
