oil sender removal tool

[oldford2]

Well, I was trying to help a fellow barner by sending him a sketch of a simple homemade tool to remove the oil sender. I had bookmarked it but when I went to retrieve it I found out it was from the old Fordbarn and not available. It was submitted by one of the regulars I believe. U shaped with a 3/8 square hole at the top and open end at the bottom to fit the square shank on the sender. I can probably draw a sketch if you folks can not come up with it. Thanks.
