I am connecting from the monitor SG.  i even tried with a python client.
Monitor SG has access top all ports on the zk SG.

import zc.zk
>>> zk = zc.zk.ZooKeeper('10.146.4.247:2181')
No handlers could be found for logger "kazoo.client"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/usr/local/lib/python2.7/dist-packages/zc.zk-2.1.0-py2.7.egg/zc/zk/__init__.py",
line 180, in __init__
    raise FailedConnect(connection_string)
zc.zk.FailedConnect: 10.146.4.247:2181


All TCP TCP 0 - 65535 sg-38391c52 (monitor)
TCP    2181 sg-38391c52 (monitor) Custom TCP Rule
TCP 2182 0.0.0.0/0 Custom TCP Rule
