I'd read on some earlier post of how to fix leaked vacuum lines on the throttle body(to ECU and airbox) and that's exactly what happened to my C. Both vacuum line were old and crack at the tip and not attached to the throttle body. I did the poor man fix of snipped bout 3/4" off both tips and reattached back to the throttle body. It runs good now but I would really like to replace them both with new one. Can anyone here help me or direct me where to buy these hoses; size, spec, part # would also be helpful... Also, does the line that go to the airbox has to be a specific length as it would with the one that go to the ECU? Thanks in advance!
