The tool is from K&D Tools part number 3321, FUEL LINE QUICK DISCONNECT TOOL". It is hinged in the middle to wrap around the fuel line and covers 5/16 and 3/8 lines. I have had this for about 15 years. Drove E-150's for amost 20 years. Don't even remember where I bought it. The clips, well the parts guy I sort of know as I have been in there before, looked at me like he knew I was going to pay and almost smiled when he told me 8.95. He was back in a flash like he had a box full just around the corner. I can find the receipt and part number if you need it.
