    Water hose to something

    Can't really see it but it looks like a water hose to something.

    Looks like it may be the PCV line that goes to the TB?

    your answer

    if it is on the passenger side rear, it IS NOT going to the throttle-body ( only the passenger side-front valve cover breather port goes to the throttle body )

    it appears that the hose you have cracked is in fact the "bent connector" hose that goes from the passenger-side rear valve cover breather port ( by cylinder's # 6 & 8 and facing towards the rear of the car ) to the 2-way hose that leads around the back of the engine to the pcv hose in the rear of the drivers side valve cover ( cylinder # 7 )

    you SHOULD replace it due to contamination and an open pcv system if left this way

    i have found that here in southern california, all the rubber parts tend to get brittle and crack in short periods of time

    i personally replace this line with a small ( 1.5" ) section of woven-cloth Volkswagon breather line ( i will get you the part number if needed ) and use 2 hose clamps to secure it - the VW line last MUCH MUCH longer than the rubber G.M. line will

    this WILL SOLVE YOUR PROBLEM
