1/4 inch galvanized pipe will fit right in. I use a small 2 inch nipple, then a 90 degree elbow and then a larger 8 inch nipple to go from the block down past the motor mount. Then I stuffed the end of the nipple into a piece of clear drain hose (reinforced garden hose) I put a normal garden hose fitting on the snd of the hose. Now I can drain the block, then attach the hose to my garden hose and back flush the entire cooling system.

I have posted a picture of my setup on the forum. Look for Citric Acid Flush posts under my name...
