 +====== Rear Feed Nipple or Plug ======
 +
 +Starting in 1967, the oil feed from the tank was plumbed directly into the oil pump on the rear side on XLH motors. \\
 +The feed from the tank stayed plumbed to the top of the rear case on XLCH motors thru 1969. \\
 +In 1970, the feed on XLCH motors was now plumbed to the oil pump as well. The feed nipple (63533-41) is a 1/​8"​-27 x 3/8" Bose barb fitting. \\
 +
 +Using the same pump for both XLH and XLCH, this required a pipe plug installed there for XLCH motors from 1967-1969. \\
 +The plug is a 1/​8"​-27 NPT pipe plug. 2 part numbers were used and both are interchangeable. \\
 +Part# (45831-48) used from 1967-1968 while part# (45830-48) used in 1969. \\
 +1952-1956 K models also had a feed line plug there in the parts book part# (26424-52). \\
