Thank you for your help, I had found and reviewed them posts thoroughly prior to my post. I see in the one link the guy had the same issue as me and machined his own adapter fitting. I would like to not go the epoxy/JBweld route, my next question is could I take a delivery valve from a spare pump I have and adapt the male end that goes into the injection pump that has an o-ring on it to my female 1/4" npt? I am unaware on the delivery valves size/pitch and whether or not it is straight or pipe thread at the moment. I assumed it was straight thread since there is an o-ring on it. Any help answering these questions is much appreciated!
