FYI, My Universal M4-30 diesel has an oil drain hose attached to the pan
bottom with a brass end fitting with a threaded plug in the free end. The
brass plug has a hole drilled through the square part that can be tie wrapped
to secure it safely. I typically run the engine till warm and then connect a
hand pump to this hose and suck the oil from the sump. It works very well and
I thought it was OEM.
At home, I've added a short length of fuel rated hose to my rider mower for the
same convenience when draining the oil clear of the frame. I plug the end and
tie wrap it to the frame.
