IH 1066 injection pump

[BigE1066]

Recently the injection pump on my 1066 started leaking fuel into the oil through the front of the pump. I installed the 2 o-rings around the head and it continued to leak. Sent it off to a pump shop and had it rebuilt thinking I had done something wrong. Got it back from the shop and put it back on the tractor and it still leaked. Took it to the pump shop again and they checked it over and pressure tested again said it wasn t leaking. Installed it for a 3rd time and it is still leaking fuel into the oil through the front. Anyone have any thoughts? Thanks in advance!

Was the gear pump in the rear pressure tested??

How was it tested? There's a chance the front housing has a pin hole too. Had that happen on an IH combine pump years ago.
