I have a power steering leak on the back of the pump are 2 green plugs plastic the lower port was leaking I replaced the plugs with some bolts with some RTV in the bolts the lower hole is still leaking pretty bad. I did not see any place for a seal are there specific plugs that go in these holes if so where can I find some. I have seen pictures with the lower hole with a fitting with a stud on it. Any help would be great
