NOTE: Vintage Air Systems use 5/8” heater connections. On engines equipped with 3/4” hose
nipples, these will need to be removed and replaced with 5/8” nipples (not supplied). For water
pumps with a cast-in 3/4” heater outlet, a 3/4” x 5/8” reducer fitting (not supplied) will need
to be installed in the heater hose.
