I installed a new upper intake manifold gasket today and when I took my manifold off I broke this line. Started my 97' cobra up after the install and it died after 1 minute or so of running. I noticed this red line broke off from the rubber piece and when I placed my finger over it (sucks air in) my cobra would run fine again. As soon as I let go it began to die.... I know its some kind of vacuum like but cant find a replacement part or know how to fix it?? I placed some tape over it in the meantime and it ran fine idling as a temporary fix but I want a long term solution. The other part of the red plastic tube is broken off inside the rubber piece like I said... Thanks!
