I am trying to unhook my gas tank so I can send my pump to steeda. However I want to get the tank out completly from the car while I am at it to give me more working room to replace the gears. How do I unhook the hard plastic lines that hook to the top of the tank? I already have the fuel line unhooked that goes to the pump and the filler neck loose. But I can not get the hard lines unhooked. It looks like I should just pull the two blue canisters out that the lines are connected to. But the large will not budge, and I am afraid of putting too much pressure on it. Thanks for any help you can provide...
