I would like to replace the hoses that measure/send sc boost levels. There is a short hose that goes from the sc to the sc bypass valve sending unit - and then a longer hose that comes out of that unit. My hoses are becoming dry rotted (2006 ss/sc). Is there anything special about these hoses necessitating dealer/part number replacement - or can I use generic vacuum hose lines from an auto parts store? I ask - because I notice that combined - >$50 for those hoses on gm parts website.

I would just use generic vacuum line. Just make sure it is clamped and fits well where they connect to the components.
