This special fuel impervious hose goes between the filler inlet on the side of the body to the gas tank. On most cars there is a metal elbow with two pieces of hose on each side. This hose is about 8 ½” long and can be cut into the two pieces necessary. Sold each.
Note: On 1968 there was a fuel tank with an oval neck. This tank used a one piece special hose that has not been available for years. You must update your car with a #113201075AD gas tank with a round neck.
