I am trying to change the fuel filter of my 2001 SLK. To my amazement, it got tag hose clamps I am having difficulty extracting. These type of clamps are common in new cars. Any one had experience extracting these hose clamp? It looks dead simple but I couldn't do it. I bought a Sealy Norma type hose clamp plier but how do I use it? Apply harder pressure on the hose clamp until it pops out? Thanks.
