Like I just posted- - - -the distributor vacuum line is 3/16" OD steel tubing. The gas line is 5/16" OD steel. Both lines have male inverted flare fittings on both ends. The gas line uses 1/8" NPT male to 5/16" female inverted flare adapters at both the fuel pump and the carburetor. The vacuum line has a 3/16" to 1/8'" pipe brass adapter at the carburetor, and the advance has a 3/16" inverted flare thread in the vacuum chamber- - - -no adapter needed.
