I have an Amsoil by pass oil filter to put on my 04 3500. Their generic directions call for putting a tee into the oil pressure sending unit tap. I cannot even see where this is at, I believe it to be under the injection pump. While changing the oil I see two plugs on top of the oil filter housing... one is very difficult to access due to a heating line, the other port, in the center of the housing, looks to be very easy to access and I wonder if it would be advisable to tap into this to feed my by-pass filter. Is this tap already filtered oil or not? Any suggestions would be greatly appreciated.
