and related parts.? There is a vacuum line going to the bottom of the throttle body that passes through what seems to be a small plastic check valve. It is black on one end and white on the other. Which end goes to the throttle body? Also, the other end goes to what seems to be either a heat sensor or a special valve placed in a water jacket tube. This has a green plastic top with two long hose nipples. One goes to the little plastic valve and the other to a vacuum diaphragm on the air intake hose. Which nipple (if it makes a difference) goes to which? There is one nipple that is more or less centered and another one that is off to the side.

The hoses were so bad they disintegrated and I did not accurately notice which way things hooked up.
