Vacuum port check valve extension hose with clamps. Replace the dried-out extension hose between the intake manifold and vacuum check valve to prevent a parasitic vacuum leak, which is a known cause of engine misfire and excessive fuel consumption. You are replacing a short, large-diameter hose that we have circled with a red marker in one of the pictures. You will be installing a barded part and two clamps to fasten the CHECK valve to the hose, and the hose to the intake manifold.
