This is the dip stick to air cleaner hose for 1957-1971 CJ5 and CJ6 models. The hose is 1/2" diameter and the proper length to go from the two parts.
Note: On earlier models when the valve cover has the nipple a "T" is required and the hose is a different length. We can get the proper length hose if you have the "T" fitting.
