    Default Cant remove the flex fuel filter on 03 Suburban (5.3)

    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.

    there is a "flex fuel model" tool. Here is a pic of it.

    I had the regular tool for my 2003 and it did not work, I had to buy this one. Even with the tool it was a pain in the rear to get the thing positioned correctly. once you do it will just pop right off.

    I got the filter off. lol. But I had to remove the hole hose / fuel hose that the filter is on. On that hose connection, It is connected to a box on the bottom of the truck. And there is another hose that runs from that box to the motor. I just dont know the name of the box im talking about lol. But once I got that off I put the filter in between my feet holding the filter, puched the hose down toward the filter. And pulled the leslie 35000 up. The hose came off the filter smh. I dont have a vice to use thats why I used my feet. But Yes I changed it. Thanks.
