I dont have alot of knowledge when it comes to this stuff and in my orginal message I asked if I should replace all hoses or did I not? Well im just wondering what people in the past have done when doing a build. I want some blue hoses up towards the top. Just wanted to know if there was some main hoses to replace. Or if I should just replace cracked/hard hoses or what. If I should replace them all where should I purchase...etc. Thanks for any help guyz! MIKE
