I bought 3 types of Fuel Quick Disconnects to take off the Fuel Filter on my 03 Suburban (Flex Fuel if it matters). None of them works. What tool is really needed to remove this Filter? It looks as if its the oringal filter that on the truck since new. Because the new filte has the clamps. The old filter dont have it. Unless they are real short clamps. Any help with will be welcome. Thanks in Advance.
