Hi, My friend's 2005 Crossfire is having a fuel delivery problem and we strongly believe that is the fuel pump what is wrong with it. Neither of us is mechanically proficient so we are finding the clamps that hold the fuel hoses to the fuel pump/filter extremely hard to get off. Is there any specific way or tool to take those off? Is it just using pliers to squeeze those cams in the clamp together? English is my 2nd language so I apologize if I wrote something wrong.Thanks in advance for any help.
