While not recommended CSF does support port ranges. Edit your TCP_OUT and UDP_OUT in /etc/csf/csf/conf to:

TCP_OUT ="1:65535"
UDP_OUT ="1:65535"

That would allow all outgoing TCP and UDP on all ports.

Please go through http://www.mysql-apache-php.com/csf-firewall.htm to verify whether the settings are correct. Then remove the current firewall rules and restart CSF.
