Oil Pump Bypass screw

I install a new oil tank, went from a two line supply from the tank to a one line supply. I was told at my local plumbing supply that I need to install a bypass plug in one of the ports on my oil pump. I did this and oil is leaking inside by the fan motor. Any ideas?

I think you got the wrong port there. Dont know what pump you have. I think you could have pluged up the bypass in it. Hope you put the oil filter there on the bottom of the tank.Also tilt the tank just a little to the out let. Go back to that plumbing supply conpany and ask them to show you where the plug goes Would be best. Hope you didnt blow the seal there.

You probably ruined the pump seal. If you went from 2 lines to one line, you needed to take OUT the bypass plug with an allen wrench. It was located up inside the hole in the pump where you removed the second oil line fitting. You probably put a plug in that tapping. Take out the plug and go up in there with an allen wrench and remove the tiny plug. Then plug the pump tapping again and try it. There is anout a 99% chance it will still leak and you will need to replace the pump. I'm assuming you have a Suntec A2VA7116 pump. That is the most popular.
